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: VALIDATED

Description

Transcript Variant: This variant (2) includes an additional exon in the 5' region and thus differs in its 5' UTR and initiates translation from an alternate start codon, and it also uses an alternate in-frame splice site in the 5' coding region, compared to variant 1. The encoded isoform (b) has a distinct N-terminus and is shorter than isoform a.
