Chain A (IFNL1_HUMAN | Q8IU54)

molecular function
	GO:0005125	cytokine activity	Functions to control the survival, growth, differentiation and effector function of tissues and cells.
	GO:0032003	interleukin-28 receptor binding	Interacting selectively and non-covalently with the interleukin-28 receptor.
	GO:0005102	receptor binding	Interacting selectively and non-covalently with one or more specific sites on a receptor molecule, a macromolecule that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function.
biological process
	GO:0007259	JAK-STAT cascade	Any process in which STAT proteins (Signal Transducers and Activators of Transcription) and JAK (Janus Activated Kinase) proteins convey a signal to trigger a change in the activity or state of a cell. The JAK-STAT cascade begins with activation of STAT proteins by members of the JAK family of tyrosine kinases, proceeds through dimerization and subsequent nuclear translocation of STAT proteins, and ends with regulation of target gene expression by STAT proteins.
	GO:0051607	defense response to virus	Reactions triggered in response to the presence of a virus that act to protect the cell or organism.
	GO:0045087	innate immune response	Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.
	GO:0045581	negative regulation of T cell differentiation	Any process that stops, prevents, or reduces the frequency, rate or extent of T cell differentiation.
	GO:0008285	negative regulation of cell proliferation	Any process that stops, prevents or reduces the rate or extent of cell proliferation.
	GO:0032696	negative regulation of interleukin-13 production	Any process that stops, prevents, or reduces the frequency, rate, or extent of interleukin-13 production.
	GO:0032714	negative regulation of interleukin-5 production	Any process that stops, prevents, or reduces the frequency, rate, or extent of interleukin-5 production.
	GO:0043381	negative regulation of memory T cell differentiation	Any process that stops, prevents, or reduces the rate of memory T cell differentiation.
	GO:0045892	negative regulation of transcription, DNA-templated	Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.
	GO:0002829	negative regulation of type 2 immune response	Any process that stops, prevents, or reduces the frequency, rate, or extent of a type 2 immune response.
	GO:0046427	positive regulation of JAK-STAT cascade	Any process that activates or increases the frequency, rate or extent of the JAK-STAT signaling pathway activity.
	GO:0045345	positive regulation of MHC class I biosynthetic process	Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of MHC class I.
	GO:0050778	positive regulation of immune response	Any process that activates or increases the frequency, rate or extent of the immune response, the immunological reaction of an organism to an immunogenic stimulus.
	GO:0032729	positive regulation of interferon-gamma production	Any process that activates or increases the frequency, rate, or extent of interferon-gamma production. Interferon-gamma is also known as type II interferon.
	GO:0045893	positive regulation of transcription, DNA-templated	Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription.
	GO:0042531	positive regulation of tyrosine phosphorylation of STAT protein	Any process that activates or increases the frequency, rate or extent of the introduction of a phosphate group to a tyrosine residue of a STAT (Signal Transducer and Activator of Transcription) protein.
cellular component
	GO:0005576	extracellular region	The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
	GO:0005615	extracellular space	That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
	GO:0032002	interleukin-28 receptor complex	A protein complex that binds interleukin-28 and interleukin-29. It is composed of an alpha and a beta receptor subunit (in human IFNLR1/IL28Ralpha & IL10RB) and either Interleukin-28 (IFNL2 or IFNL3) or Interleukin-29 (IFNL1).
	GO:0005622	intracellular	The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.

Chain B (INLR1_HUMAN | Q8IU57)

molecular function
	GO:0004896	cytokine receptor activity	Combining with a cytokine and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.
	GO:0005515	protein binding	Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
biological process
	GO:0019221	cytokine-mediated signaling pathway	A series of molecular signals initiated by the binding of a cytokine to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription.
	GO:0051607	defense response to virus	Reactions triggered in response to the presence of a virus that act to protect the cell or organism.
	GO:0002385	mucosal immune response	An immune response taking place in mucosal tissues, including those of the intestinal tract, nasal and upper respiratory tract, and genital tract.
	GO:0008285	negative regulation of cell proliferation	Any process that stops, prevents or reduces the rate or extent of cell proliferation.
	GO:0050691	regulation of defense response to virus by host	Any host process that modulates the frequency, rate, or extent of the antiviral response of a host cell or organism.
	GO:0034342	response to type III interferon	Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a type III interferon stimulus. Interferon lambda is the only member of the type III interferon found so far.
cellular component
	GO:0016021	integral component of membrane	The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
	GO:0032002	interleukin-28 receptor complex	A protein complex that binds interleukin-28 and interleukin-29. It is composed of an alpha and a beta receptor subunit (in human IFNLR1/IL28Ralpha & IL10RB) and either Interleukin-28 (IFNL2 or IFNL3) or Interleukin-29 (IFNL1).
	GO:0016020	membrane	A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
	GO:0005886	plasma membrane	The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
