Summary: Enables epidermal growth factor receptor binding activity; phosphoprotein binding activity; and protein kinase binding activity. Involved in several processes, including blood vessel maturation; macrophage fusion; and positive regulation of neutrophil apoptotic process. Located in apical plasma membrane; basolateral plasma membrane; and cell surface. Part of protein-containing complex. Is active in glutamatergic synapse; postsynapse; and presynapse. Biomarker of borna disease and cholestasis. Human ortholog(s) of this gene implicated in breast carcinoma (multiple); carcinoma (multiple); and prostate cancer. Orthologous to human CD44 (CD44 molecule (IN blood group)). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
