Chain A   (ISK5_HUMAN | Q9NQ38)
molecular function
    GO:0030414    peptidase inhibitor activity    Stops, prevents or reduces the activity of a peptidase, any enzyme that catalyzes the hydrolysis peptide bonds.
    GO:0004867    serine-type endopeptidase inhibitor activity    Stops, prevents or reduces the activity of serine-type endopeptidases, enzymes that catalyze the hydrolysis of nonterminal peptide bonds in a polypeptide chain; a serine residue (and a histidine residue) are at the active center of the enzyme.
biological process
    GO:0042640    anagen    The growth phase of the hair cycle. Lasts, for example, about 3 to 6 years for human scalp hair.
    GO:0009913    epidermal cell differentiation    The process in which a relatively unspecialized cell acquires specialized features of an epidermal cell, any of the cells making up the epidermis.
    GO:0030855    epithelial cell differentiation    The process in which a relatively unspecialized cell acquires specialized features of an epithelial cell, any of the cells making up an epithelium.
    GO:0030198    extracellular matrix organization    A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an extracellular matrix.
    GO:0035315    hair cell differentiation    The process in which a relatively unspecialized cell acquires specialized features of a hair cell.
    GO:0016525    negative regulation of angiogenesis    Any process that stops, prevents, or reduces the frequency, rate or extent of angiogenesis.
    GO:0002787    negative regulation of antibacterial peptide production    Any process that stops, prevents, or reduces the frequency, rate, or extent of antibacterial peptide production.
    GO:0050777    negative regulation of immune response    Any process that stops, prevents, or reduces the frequency, rate or extent of the immune response, the immunological reaction of an organism to an immunogenic stimulus.
    GO:0010466    negative regulation of peptidase activity    Any process that stops or reduces the rate of peptidase activity, the hydrolysis of peptide bonds within proteins.
    GO:0045861    negative regulation of proteolysis    Any process that stops, prevents, or reduces the frequency, rate or extent of the hydrolysis of a peptide bond or bonds within a protein.
    GO:1900004    negative regulation of serine-type endopeptidase activity    Any process that stops, prevents or reduces the frequency, rate or extent of serine-type endopeptidase activity.
    GO:1902572    negative regulation of serine-type peptidase activity    Any process that stops, prevents or reduces the frequency, rate or extent of serine-type peptidase activity.
    GO:0045580    regulation of T cell differentiation    Any process that modulates the frequency, rate or extent of T cell differentiation.
    GO:0030155    regulation of cell adhesion    Any process that modulates the frequency, rate or extent of attachment of a cell to another cell or to the extracellular matrix.
cellular component
    GO:0005938    cell cortex    The region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins.
    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:0005783    endoplasmic reticulum    The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).
    GO:0005789    endoplasmic reticulum membrane    The lipid bilayer surrounding the endoplasmic reticulum.
    GO:0097209    epidermal lamellar body    A specialized secretory organelle found in keratinocytes and involved in the formation of an impermeable, lipid-containing membrane that serves as a water barrier and is required for correct skin barrier function.
    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: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:0048471    perinuclear region of cytoplasm    Cytoplasm situated near, or occurring around, the nucleus.
