Summary: This gene encodes a transcription factor containing a POU homeodomain that plays a key role in embryonic development and stem cell pluripotency. Aberrant expression of this gene in adult tissues is associated with tumorigenesis. This gene can participate in a translocation with the Ewing's sarcoma gene on chromosome 21, which also leads to tumor formation. Alternative splicing, as well as usage of alternative AUG and non-AUG translation initiation codons, results in multiple isoforms. One of the AUG start codons is polymorphic in human populations. Related pseudogenes have been identified on chromosomes 1, 3, 8, 10, and 12. [provided by RefSeq, Oct 2013]

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.

See identical proteins and their annotated locations for NP_001167002.1

Status: REVIEWED

Description

Transcript Variant: This variant (3) differs in the 5' UTR, lacks a portion of the 5' coding region, and initiates translation at a downstream in-frame non-AUG (CUG) start codon, compared to variant 1. The resulting isoform (2, also known as OCT4B-190) is shorter at the N-terminus, compared to isoform 1. Variants 2 and 3 encode the same isoform (2). This variant may encode an additional isoform through the use of an alternative downstream AUG start codon. Use of alternate start codons and the non-AUG start codon is described in PMID:19489092.

Status: REVIEWED

Description

Transcript Variant: This variant (5, also known as OCT4B) differs in the 5' UTR, lacks a portion of the 5' coding region, and initiates translation at an alternate AUG start codon, compared to variant 1. The resulting isoform (3, also known as OCT4B-265) is shorter and has a distinct N-terminus, compared to isoform 1. This variant represents an allele of variant 2 that contains an AUG start codon that is polymorphic in human populations (see rs3130932). This variant may encode additional isoforms through the use of alternative downstream AUG and non-AUG start codons, as described in PMID:19489092.
