Summary: Enables several functions, including CD4 receptor binding activity; protein antigen binding activity; and protein phosphatase binding activity. Involved in release of sequestered calcium ion into cytosol. Acts upstream of or within several processes, including positive regulation of macromolecule metabolic process; protein phosphorylation; and regulation of T cell differentiation. Located in cell-cell junction. Colocalizes with plasma membrane. Is expressed in several structures, including 2-cell stage embryo; nervous system; neural ectoderm; sensory organ; and thymus primordium.

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.
