Summary: This gene encodes a calcium-responsive transactivator which is an essential subunit of a neuron-specific chromatin-remodeling complex. The structure of this gene is similar to that of the SS18 gene. Mutations in this gene are involved in amyotrophic lateral sclerosis (ALS). Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2014]

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.

Status: REVIEWED

Description

Transcript Variant: This variant (2) has an additional exon in the 5' region and an alternate splice acceptor site, which results in translation initiation at a downstream AUG start codon, compared to variant 1. The resulting isoform (2) has a shorter N-terminus, compared to isoform 1.

Status: REVIEWED

Description

Transcript Variant: This variant (3) has an additional exon and an additional segment in the 5' region and lacks an internal segment in the 3' terminal region, compared to variant 1. This variant is represented as non-coding because the absence of the 3' internal segment renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
