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_001191439.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) uses an alternate splice site that causes a frameshift in the 3' coding region, compared to variant 1, resulting in an isoform (2) with a distinct and shorter C-terminus, compared to isoform 1.
