Summary: This gene encodes a member of the cysteine-aspartic acid protease (caspase) family. Caspases mediate cellular apoptosis through the proteolytic cleavage of specific protein substrates. The encoded protein may function in stress-induced cell death pathways, cell cycle maintenance, and the suppression of tumorigenesis. Increased expression of this gene may play a role in neurodegenerative disorders including Alzheimer's disease, Huntington's disease and temporal lobe epilepsy. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jan 2011]

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.

See identical proteins and their annotated locations for NP_001215.1

Status: REVIEWED

Description

Transcript Variant: This variant (2) contains an alternative 5' terminal exon (resulting in translation initiation from an in-frame downstream AUG), and an additional internal exon compared to variant 1. The latter causes a frame-shift, and early translation termination, rendering this transcript a candidate for nonsense-mediated mRNA decay (NMD). However, this variant is represented as protein-coding as the encoded short isoform (2, also known as ICH-1S) has been shown to be expressed in vivo (PMID:12598307), and to function as a negative regulator of apoptosis (PMID:8087842).

Status: REVIEWED

Description

Transcript Variant: This variant (3) lacks an exon and uses an alternate splice site in the coding region, which results in a frameshift and early stop codon, compared to variant 1. The encoded isoform (3) is shorter and has a distinct C-terminus, compared to isoform 1.
