Gene: Muc4 (mucin 4, cell surface associated) Rattus norvegicus
Symbol: Muc4
Name: mucin 4, cell surface associated
RGD ID: 621331
Description: Enables ErbB-2 class receptor binding activity. Involved in several processes, including estrous cycle; negative regulation of T cell mediated cytotoxicity directed against tumor cell target; and negative regulation of cell adhesion. Located in apical plasma membrane; extracellular space; and microvillus membrane. Part of protein-containing complex. Biomarker of cholangiocarcinoma; corneal neovascularization; mucositis; and otitis media. Human ortholog(s) of this gene implicated in pancreatic cancer. Orthologous to human MUC4 (mucin 4, cell surface associated); INTERACTS WITH 1-naphthyl isothiocyanate; 17alpha-ethynylestradiol; 17beta-estradiol.
Type: protein-coding
RefSeq Status: VALIDATED
