Epiregulin: Ligand of the EGF receptor/EGFR and ERBB4. May be a mediator of localized cell proliferation. As a mitogen it may stimulate cell proliferation and/or angiogenesis.
Protein type: Membrane protein, integral
Chromosomal Location of Human Ortholog: 4q13.3
Cellular Component: extracellular space; integral to plasma membrane; extracellular region
Molecular Function: protein binding; growth factor activity; epidermal growth factor receptor binding
Biological Process: response to peptide hormone stimulus; nerve growth factor receptor signaling pathway; wound healing; activation of MAPK activity; positive regulation of interleukin-6 biosynthetic process; positive regulation of smooth muscle cell proliferation; female meiosis; negative regulation of smooth muscle cell differentiation; negative regulation of cell proliferation; primary follicle stage, oogenesis; positive regulation of fibroblast proliferation; positive regulation of epidermal growth factor receptor activity; cell-cell signaling; positive regulation of innate immune response; positive regulation of cell proliferation; ovarian cumulus expansion; angiogenesis; negative regulation of epithelial cell proliferation; positive regulation of cytokine production; epidermal growth factor receptor signaling pathway; anatomical structure morphogenesis; fibroblast growth factor receptor signaling pathway; phosphoinositide-mediated signaling; positive regulation of mitosis; cytokine and chemokine mediated signaling pathway; positive regulation of cytokine biosynthetic process; keratinocyte proliferation; luteinizing hormone signaling pathway; oocyte maturation; keratinocyte differentiation; ovulation; organ morphogenesis; positive regulation of protein kinase activity; mRNA transcription; innate immune response; negative regulation of transcription, DNA-dependent; positive regulation of DNA replication; positive regulation of phosphorylation
