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.

mRNA and Protein(s)

NM_001317926.2 → NP_001304855.1 serine/threonine-protein kinase N3 isoform 2

Status: VALIDATED

Description

Transcript Variant: This variant (2) uses an alternate splice site in the penultimate exon, compared to variant 1, resulting in a novel 3' coding region and shorter 3' UTR. It encodes isoform 2 which is shorter and has a distinct C-terminus, compared to isoform 1.
