Summary: This gene encodes a member of the heterogeneous family of basic, proline-rich, human salivary glycoproteins. The encoded preproprotein undergoes proteolytic processing to generate one or more mature isoforms before secretion from the parotid glands. Multiple alleles of this gene exhibiting variations in the length of the tandem repeats, polymorphic cleavage sites and polymorphic stop codons have been identified. This gene is located in a cluster of closely related salivary proline-rich proteins on chromosome 12. [provided by RefSeq, May 2023]

What's a GeneRIF?

pRb2/p130 cytoplasmic delocalization can lead to cell cycle deregulation
Title: pRb2/p130 localizes to the cytoplasm in diffuse gastric cancer.
Our studies suggested that pRb2/p130-complexes bind to the ER-alpha promoter and could be involved in the transcriptional regulation of the ER-alpha gene by altering chromatin structure and DNA methylation pattern.
Title: The regulation of ER-alpha transcription by pRb2/p130 in breast cancer.
Ezh2 competes with HDAC1 in binding to pRb2/p130, disrupting their occupancy on the cyclin A promoter.

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.
