Summary: Predicted to enable calcium channel activity. Involved in cerebellar Purkinje cell differentiation; cerebellar granular layer development; and regulation of neuron apoptotic process. Acts upstream of or within negative regulation of apoptotic signaling pathway; negative regulation of neuron apoptotic process; and response to ischemia. Located in Golgi apparatus; endoplasmic reticulum; and membrane raft. Is expressed in several structures, including alimentary system; brain; genitourinary system; immune system; and white fat. Orthologous to human FAIM2 (Fas apoptotic inhibitory molecule 2). [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.
