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.

Status: VALIDATED

Description

Transcript Variant: This variant (4) has multiple differences in the 5' UTR and 5' coding region, and initiates translation at an alternate start codon compared to variant 1. The resulting isoform (b) has a shorter and distinct N-terminus compared to isoform a. Variants 4 and 5 both encode the same isoform (b).

Status: VALIDATED

Description

Transcript Variant: This variant (5) uses an alternate splice junction at the 5' end of an internal exon, resulting in translation initiation at an alternate start codon compared to variant 1. The encoded isoform (b) has a shorter and distinct N-terminus compared to isoform a. Variants 4 and 5 both encode the same isoform (b).

Description

Transcript Variant: This variant (7) has an alternate first exon in place of the first two exons compared to variant 1. This variant is represented as non-coding because it lacks a large portion of the coding region, including the translational start codon, found in variant 1.
