Can regulate cell morphology in cooperation with activated RAC1. Plays a role in Th2 (T helper cells) development and/or activation, perhaps by interfering with ZAP70 signaling (By similarity). {ECO:0000250, ECO:0000269|PubMed:12651066, ECO:0000269|PubMed:15023524}. |PH| |filopodium| |cytoskeleton| |perinuclear region of cytoplasm| |membrane| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp308|Rapamycin 2μM plus FK-506 5μM R07 exp308]]|2.01| ^Gene^Correlation^ |[[:human genes:r:rrm1|RRM1]]|0.438| |[[:human genes:p:polr2j3|POLR2J3]]|0.422| Global Fraction of Cell Lines Where Essential: 0/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/26| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|0/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 3132 * **Expression level (log2 read counts)**: 4.56 {{:chemogenomics:nalm6 dist.png?nolink |}}
