Also known as: PBF; C21orf1; C21orf3; PTTG1IP1
Summary: This gene encodes a single-pass type I integral membrane protein, which binds to pituitary tumor-transforming 1 protein (PTTG1), and facilitates translocation of PTTG1 into the nucleus. Coexpression of this protein and PTTG1 induces transcriptional activation of basic fibroblast growth factor. Alternatively spliced transcript variants have been found for this gene.

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: REVIEWED

Description

Transcript Variant: This variant (2) lacks 3 consecutive exons, which cause a frame-shift compared to variant 1. The resulting shorter isoform (2) has a distinct C-terminus compared to isoform 1.

NR_104597.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (3) lacks an exon in the mid-region compared to variant 1. It is represented as non-coding because the use of the supported translational start codon, as used in variant 1, renders this transcript a candidate for nonsense-mediated mRNA decay (NMD).
