======= TBC1D8B ======= == Gene Information == * **Official Symbol**: TBC1D8B * **Official Name**: TBC1 domain family member 8B * **Aliases and Previous Symbols**: N/A * **Entrez ID**: [[https://www.ncbi.nlm.nih.gov/gene/?term=54885|54885]] * **UniProt**: [[https://www.uniprot.org/uniprot/Q0IIM8|Q0IIM8]] * **Interactions**: [[https://thebiogrid.org/search.php?search=TBC1D8B&organism=9606|BioGRID]] * **PubMed articles**: [[https://www.ncbi.nlm.nih.gov/pubmed/?term=gene%20TBC1D8B|Open PubMed]] * **OMIM**: [[https://omim.org/entry/301027|Open OMIM]] == Function Summary == * **Entrez Summary**: This gene encodes a protein with a TBC (Tre-2/Bub2/CDC16) domain. Some mammalian proteins with this domain have been shown to function as Rab-GAPs by binding to specific Rab proteins and affecting their GTPase activity. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2011]. * **UniProt Summary**: May act as a GTPase-activating protein for Rab family protein(s). |TBC| |GRAM| |cell| |activation of GTPase activity| |Rab GTPase binding| |GTPase activator activity| |positive regulation of GTPase activity| |regulation of GTPase activity| |calcium ion binding| |positive regulation of hydrolase activity| |intracellular protein transport| |regulation of hydrolase activity| |positive regulation of catalytic activity| |protein transport| |intracellular transport| |peptide transport| |amide transport| |cellular protein localization| |cellular macromolecule localization| |establishment of protein localization| |positive regulation of molecular function| |establishment of localization in cell| |nitrogen compound transport| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp471|Cholesterol 0.003 to 0.006 to 0.1μM on day2 then day6 R08 exp471]]|2.18| ^Gene^Correlation^ |[[:human genes:r:rrm1|RRM1]]|0.476| Global Fraction of Cell Lines Where Essential: 0/694 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/26| |bone|0/26| |breast|0/30| |central nervous system|0/49| |cervix|0/4| |colorectal|0/17| |esophagus|0/11| |fibroblast|0/1| |gastric|0/14| |kidney|0/18| |liver|0/19| |lung|0/72| |lymphocyte|0/16| |ovary|0/25| |pancreas|0/22| |peripheral nervous system|0/15| |plasma cell|0/12| |prostate|0/1| |skin|0/20| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/28| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 15412 * **Expression level (log2 read counts)**: 5.68 {{:chemogenomics:nalm6 dist.png?nolink |}}
