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.

NM_001163640.1 → NP_001157112.1 beta-chimaerin isoform 2

See identical proteins and their annotated locations for NP_001157112.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) uses an alternate, upstream transcription initiation site, uses a distinct start codon and contains several additional exons, compared to variant 1. The resulting protein (isoform 2, also referred to as beta2-chimerin) has a much longer and distinct N-terminus compared to isoform 1.
