Predicted to enable RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; p53 binding activity; and transcription coregulator activity. Predicted to be involved in several processes, including DNA damage response, signal transduction by p53 class mediator; negative regulation of intrinsic apoptotic signaling pathway in response to DNA damage by p53 class mediator; and regulation of transcription, DNA-templated. Located in apical plasma membrane and cell surface. Is expressed in several structures, including brain; exocrine gland; genitourinary system; gut; and respiratory system. Human ortholog(s) of this gene implicated in several diseases, including allergic rhinitis; biliary tract benign neoplasm; dry eye syndrome; familial juvenile hyperuricemic nephropathy; and pancreatic cancer (multiple). Orthologous to human MUC1 (mucin 1, cell surface associated). [provided by Alliance of Genome Resources, Apr 2022]
