CRB3 crumbs cell polarity complex component 3 [Homo sapiens (human)] - Gene

Summary

Official Symbol: CRB3provided by HGNC
Official Full Name: crumbs cell polarity complex component 3provided by HGNC
Primary source: HGNC:HGNC:20237
See related: Ensembl:ENSG00000130545 MIM:609737
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
Summary: This gene encodes a member of the Crumbs family of proteins. This gene is widely expressed in epithelial tissues where the encoded protein isoforms play various roles such as the control of cytokinesis and ciliogenesis or the formation of tight junctions. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2016]
Expression: Broad expression in colon (RPKM 9.7), duodenum (RPKM 9.6) and 16 other tissues See more

What's a GeneRIF?

CRB3 strongly promotes tumor invasion and metastasis of human colon adenocarcinoma cells. Correlative expression between CRB3 and FGFR1 was consistently detected in primary and metastatic colorectal cancer patient tissues. Taking these together, CRB3 critically accelerates cell migration, namely invasion and metastasis of human colon cancers, through specific interaction to FGFR1 on colon cancer cells.
Title: Crumbs3 is a critical factor that regulates invasion and metastasis of colon adenocarcinoma via the specific interaction with FGFR1.
CRB3 DNA methylation negatively correlated with CRB3 mRNA expression. CRB3 DNA methylation was also related to pathologic stage, T stage, N stage, and M stage of ccRCC.
Title: DNA methylation of CRB3 is a prognostic biomarker in clear cell renal cell carcinoma.
CRB3 is an important regulator for breast cancer stemness, which is associated with tamoxifen resistance.Association between CRB3 and beta-catenin expression levels correlates with tamoxifen resistance of breast cancer.
Title: Elevated CRB3 expression suppresses breast cancer stemness by inhibiting β-catenin signalling to restore tamoxifen sensitivity.
We found that CRB3-induced proliferation is epidermal growth factor (EGF)-independent and occurs through a mechanism that involves secretion of the EGF-family ligand, amphiregulin (AREG)..We identified the FBD-containing protein, EPB41L4B, as an essential mediator of CRB3-driven proliferation and observed that the CRB3-dependent changes in endocytic trafficking were also dependent on EPB41L4B
Title: CRB3 and the FERM protein EPB41L4B regulate proliferation of mammary epithelial cells through the release of amphiregulin.
we report for the first time that CRB3 acts as an upstream regulator of the Hippo pathway to regulate contact inhibition by recruiting other Hippo molecules, such as Kibra and/or FRMD6, in mammary epithelial cells.
Title: CRB3 regulates contact inhibition by activating the Hippo pathway in mammary epithelial cells.
Data show different intracellular mobility patterns for crumbs 3 proteins Crb3A and Crb3B.
Title: The C-terminal domain controls the mobility of Crumbs 3 isoforms.
CRB3A recruits p114RhoGEF and its activator Ehm2 to the cell periphery using both functional motifs of its cytoplasmic tail and increases RhoA activation levels.
Title: CRB3A Controls the Morphology and Cohesion of Cancer Cells through Ehm2/p114RhoGEF-Dependent Signaling.
our data demonstrated that CRB3 may be used as a new independent favorable prognostic factor for human ccRCC
Title: Cell polarity protein CRB3 is an independent favorable prognostic factor for clear cell renal cell carcinoma.
Morg1 facilitates Par6-aPKC binding to Crb3 for definition of apical identity of epithelial cells.
Title: The WD40 protein Morg1 facilitates Par6-aPKC binding to Crb3 for apical identity in epithelial cells.
overexpression of human CRB1 and related isoforms, CRB2 and CRB3, had no effect on the levels of presenilin complex components, on NCT maturation or on PS endoproteolysis
Title: Overexpression of human CRB1 or related isoforms, CRB2 and CRB3, does not regulate the human presenilin complex in culture cells.

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.
