Located in nuclear inclusion body. Part of protein-containing complex. Is expressed in several structures, including central nervous system; early conceptus; genitourinary system; liver; and skeleton. Used to study spinocerebellar ataxia type 1.

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_001186233.1

Status: VALIDATED

Description

Transcript Variant: This variant (3) differs in the 5' UTR and uses an alternate in-frame splice junction at the 3' end of an exon compared to variant 1. The resulting isoform (b) has the same N- and C-termini but is shorter compared to isoform a. Variants 2 and 3 both encode the same isoform (b).
