Summary: Involved in mammary gland duct morphogenesis; positive regulation of T cell apoptotic process; and tissue homeostasis. Acts upstream of or within several processes, including amelogenesis; desmosome organization; and intrinsic apoptotic signaling pathway by p53 class mediator. Located in several cellular components, including Golgi apparatus; desmosome; and mitochondrion. Is expressed in several structures, including alimentary system; brain ventricle and choroid plexus; limb primordium; sensory organ; and skin. Human ortholog(s) of this gene implicated in erythrokeratodermia variabilis and mutilating palmoplantar keratoderma with periorificial keratotic plaques. Orthologous to human PERP (p53 apoptosis effector related to PMP22). [provided by Alliance of Genome Resources, Jul 2025]
Expression: Biased expression in stomach adult (RPKM 379.3), duodenum adult (RPKM 159.3) and 14 other tissues See more

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.
