Chain A   (FABP4_HUMAN | P15090)
molecular function
    GO:0005504    fatty acid binding    Interacting selectively and non-covalently with fatty acids, aliphatic monocarboxylic acids liberated from naturally occurring fats and oils by hydrolysis.
    GO:0008289    lipid binding    Interacting selectively and non-covalently with a lipid.
    GO:0005215    transporter activity    Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells.
biological process
    GO:0050873    brown fat cell differentiation    The process in which a relatively unspecialized cell acquires specialized features of a brown adipocyte, an animal connective tissue cell involved in adaptive thermogenesis. Brown adipocytes contain multiple small droplets of triglycerides and a high number of mitochondria.
    GO:0071285    cellular response to lithium ion    Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a lithium (Li+) ion stimulus.
    GO:0042632    cholesterol homeostasis    Any process involved in the maintenance of an internal steady state of cholesterol within an organism or cell.
    GO:0001816    cytokine production    The appearance of a cytokine due to biosynthesis or secretion following a cellular stimulus, resulting in an increase in its intracellular or extracellular levels.
    GO:0006469    negative regulation of protein kinase activity    Any process that stops, prevents, or reduces the frequency, rate or extent of protein kinase activity.
    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:0050729    positive regulation of inflammatory response    Any process that activates or increases the frequency, rate or extent of the inflammatory response.
    GO:0050727    regulation of inflammatory response    Any process that modulates the frequency, rate or extent of the inflammatory response, the immediate defensive reaction (by vertebrate tissue) to infection or injury caused by chemical or physical agents.
    GO:0006810    transport    The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
    GO:0019433    triglyceride catabolic process    The chemical reactions and pathways resulting in the breakdown of a triglyceride, any triester of glycerol.
    GO:0050872    white fat cell differentiation    The process in which a relatively unspecialized cell acquires specialized features of a white adipocyte, an animal connective tissue cell involved in energy storage. White adipocytes have cytoplasmic lipids arranged in a unique vacuole.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0070062    extracellular exosome    A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
    GO:0005811    lipid droplet    An intracellular non-membrane-bounded organelle comprising a matrix of coalesced lipids surrounded by a phospholipid monolayer. May include associated proteins.
    GO:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
