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_001164561.1 → NP_001158033.1 exosome complex component CSL4 isoform 2

See identical proteins and their annotated locations for NP_001158033.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) lacks two in-frame exons in the mid-coding region compared to variant 1. The resulting isoform (2) is shorter, missing an internal protein segment compared to isoform 1. Like variant 1, this variant also uses the downstream AUG.

Status: VALIDATED

Description

Transcript Variant: This variant (1) represents the predominant transcript and encodes the longest isoform (1). It contains an in-frame AUG four codons upstream from the currently annotated translation start site; however, Kozak signal strength and conservation data support the use of the annotated downstream AUG.
