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_001297642.2 → NP_001284571.1 complement C1r subcomponent-like protein isoform 3 precursor

Status: VALIDATED

Description

Transcript Variant: This variant (3) differs in the 3' UTR, and uses an alternate splice site in the 5' coding region resulting in a frameshift, compared to variant 1. The encoded isoform (3) is shorter, and has a distinct C-terminus, compared to isoform 1.

Status: VALIDATED

Description

Transcript Variant: This variant (4) lacks several exons and its 3' terminal exon extends past a splice site that is used in variant 1. This results in a novel 3' coding region and 3' UTR, compared to variant 1. The encoded isoform (4) is shorter, and has a distinct C-terminus, compared to isoform 1.
