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_001104567.1

Status: REVIEWED

Description

Transcript Variant: This variant (2) uses an alternate in-frame donor splice site in the 5' coding region compared to variant 1. This results in a shorter isoform (B) missing an internal protein segment compared to isoform A.
