biological process
    GO:0038128    ERBB2 signaling pathway    A series of molecular signals initiated by binding of a ligand to a member of the ERBB family of receptors on the surface of a cell, where the signal is transmitted by ERBB2. The pathway ends with regulation of a downstream cellular process, e.g. transcription. ERBB2 receptors are themselves unable to bind to ligands, but act as a signal-amplifying tyrosine kinase within a heterodimeric pair.
    GO:0018108    peptidyl-tyrosine phosphorylation    The phosphorylation of peptidyl-tyrosine to form peptidyl-O4'-phospho-L-tyrosine.
    GO:0098779    positive regulation of macromitophagy in response to mitochondrial depolarization    The macromitophagy process that is triggered by a detection of the loss of mitochondrial membrane potential.

A type I interferon-mediated signaling pathway is the series of molecular events generated as a consequence of a type I interferon binding to a cell surface receptor.
cellular component
    GO:1990565    HSP90-CDC37 chaperone complex    A protein kinase chaperone complex required for the proper folding, maturation and stabilization of target proteins (mostly signalling protein kinases, some steroid hormone receptors), usually during or immediately after completion of translation. The highly conserved, phosphorylated CDC37-Ser13 (vertebrates) or cdc37-Ser14 (yeast) is essential for complex assembly and target protein binding. CDC37-Ser13 (Ser14) is phosphorylated by Casein kinase II (CK2), which in turn is a target of CDC37 creating a positive feedback loop. Complex binding also prevents rapid ubiquitin-dependent proteosomal degradation of target 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: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.
