Mutations in this gene can alter the expression of other sarcomeric tropomyosin proteins, and cause cap disease, nemaline myopathy and distal arthrogryposis syndromes. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Mar 2009]. * **UniProt Summary**: Binds to actin filaments in muscle and non-muscle cells. Plays a central role, in association with the troponin complex, in the calcium dependent regulation of vertebrate striated muscle contraction. Smooth muscle contraction is regulated by interaction with caldesmon. In non-muscle cells is implicated in stabilizing cytoskeleton actin filaments. The non-muscle isoform may have a role in agonist-mediated receptor internalization. {ECO:0000250|UniProtKB:P58774, ECO:0000250|UniProtKB:P58775}. |Tropomyosin| |Tropomyosin 1| |muscle thin filament tropomyosin| |actin-myosin filament sliding| |muscle filament sliding| |structural constituent of muscle| |regulation of ATPase activity| |actin filament| |actin-mediated cell contraction| |actin filament-based movement| |actin filament binding| |actin cytoskeleton| |actin filament organization| |muscle contraction| |actin binding| |muscle system process| |supramolecular fiber organization| |protein heterodimerization activity| |actin cytoskeleton organization| |actin filament-based process| |protein homodimerization activity| |identical protein binding| |cytoskeleton organization| |regulation of hydrolase activity| |movement of cell or subcellular component| |system process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp24|Nocodazole 0.2μM R00 exp24]]|-1.91| |[[:results:exp492|iCRT14 30μM R08 exp492]]|-1.87| |[[:results:exp42|BI-6727 0.001μM R01 exp42]]|1.76| |[[:results:exp133|MKC9989 10μM R03 exp133]]|1.87| |[[:results:exp453|B02 10μM R08 exp453]]|1.88| |[[:results:exp58|UM131593 0.1μM R01 exp58]]|2.95| ^Gene^Correlation^ |[[:human genes:r:ruvbl2|RUVBL2]]|0.501| |[[:human genes:p:polr2j3|POLR2J3]]|0.453| 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**: 2719 * **Expression level (log2 read counts)**: 4.81 {{:chemogenomics:nalm6 dist.png?nolink |}}
