Official Full Name: prominin 2provided by HGNC
Primary source: HGNC:HGNC:20685
See related: Ensembl:ENSG00000155066 MIM:617160
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: PROML2
Summary: This gene encodes a member of the prominin family of pentaspan membrane glycoproteins. The encoded protein localizes to basal epithelial cells and may be involved in the organization of plasma membrane microdomains. Alternative splicing results in multiple transcript variants.

What's a GeneRIF?

Prominin2 facilitates ferroptosis resistance in epithelial and carcinoma cells. Prominin2 promotes formation of ferritin-containing multivesicular bodies and exosomes.
Title: Prominin2 Drives Ferroptosis Resistance by Stimulating Iron Export.
Prom2 protrusions primarily localize to lipid rafts and recruit cholesterol into protrusions and away from caveolae, leading to increased phosphorylation of caveolin-1, which inhibits Cdc42-dependent endocytosis
Title: Prominin-2 expression increases protrusions, decreases caveolae and inhibits Cdc42 dependent fluid phase endocytosis.
Data show the distribution and subcellular localization of prominin-2 within the kidney in situ and its release into the urine.
Title: Prominin-2 is a novel marker of distal tubules and collecting ducts of the human and murine kidney.
prominin-2, another protein in the same family as CD133/prominin-1, may not play an important functional role in the growth of human glioma and hepatocellular carcinoma cells
Title: Effect of CD133/prominin-1 antisense oligodeoxynucleotide on in vitro growth characteristics of Huh-7 human hepatocarcinoma cells and U251 human glioma cells.
Prominin-2 is widely and abundantly expressed along the epithelia of various segments of the adult male genitourinary tract.
Title: Robust expression of Prominin-2 all along the adult male reproductive system and urinary bladder.
The PROM2 gene was shown to effectively separate these two tumor(chromophobe renal cell carcinoma (RCC) and benign oncocytoma) groups by quantitative reverse transcription-PCR using fresh tissue samples, with similar trends seen on formalin-fixed tissues.
Title: Gene expression profiling separates chromophobe renal cell carcinoma from oncocytoma and identifies vesicular transport and cell junction proteins as differentially expressed genes.

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.
