This protein is a member of the Stac gene family and contains an N-terminal cysteine-rich domain and two SH3 domains. Mutations in this gene are a cause of Native American myopathy. [provided by RefSeq, Nov 2013]. * **UniProt Summary**: Required for normal excitation-contraction coupling in skeletal muscle and for normal muscle contraction in response to membrane depolarization. Required for normal Ca(2+) release from the sarcplasmic reticulum, which ultimately leads to muscle contraction. Probably functions via its effects on muscle calcium channels (PubMed:23736855, PubMed:29078335). Increases CACNA1S channel activity, in addition to its role in enhancing the expression of CACNA1S at the cell membrane. Has a redundant role in promoting the expression of the calcium channel CACNA1S at the cell membrane (By similarity). Slows down the inactivation rate of the calcium channel CACNA1C (in vitro) (PubMed:29078335). {ECO:0000250|UniProtKB:Q8BZ71, ECO:0000269|PubMed:23736855, ECO:0000269|PubMed:29078335}. |SH3 1| |C1 1| |SH3 2| |positive regulation of voltage-gated calcium channel activity| |skeletal muscle fiber development| |voltage-gated calcium channel complex| |myotube cell development| |skeletal muscle contraction| |neuromuscular synaptic transmission| |regulation of voltage-gated calcium channel activity| |positive regulation of calcium ion transmembrane transporter activity| |T-tubule| |musculoskeletal movement| |multicellular organismal movement| |positive regulation of protein localization to plasma membrane| |myotube differentiation| |muscle fiber development| |extrinsic component of cytoplasmic side of plasma membrane| |positive regulation of protein localization to cell periphery| |positive regulation of cation channel activity| |positive regulation of calcium ion transmembrane transport| |regulation of calcium ion transmembrane transporter activity| |regulation of protein localization to plasma membrane| |positive regulation of ion transmembrane transporter activity| |striated muscle contraction| |positive regulation of transporter activity| |regulation of protein localization to cell periphery| |positive regulation of calcium ion transport| |positive regulation of protein localization to membrane| |skeletal muscle tissue development| |skeletal muscle organ development| |striated muscle cell development| |positive regulation of cation transmembrane transport| |regulation of calcium ion transmembrane transport| |muscle cell development| |positive regulation of ion transmembrane transport| |regulation of cation channel activity| |regulation of protein localization to membrane| |striated muscle cell differentiation| |positive regulation of transmembrane transport| |muscle cell differentiation| |regulation of calcium ion transport| |muscle contraction| |regulation of ion transmembrane transporter activity| |regulation of transmembrane transporter activity| |positive regulation of ion transport| |regulation of transporter activity| |striated muscle tissue development| |muscle organ development| |muscle tissue development| |muscle system process| |positive regulation of cellular protein localization| |regulation of cation transmembrane transport| |regulation of metal ion transport| |anterograde trans-synaptic signaling| |chemical synaptic transmission| |trans-synaptic signaling| |synaptic signaling| |muscle structure development| |regulation of ion transmembrane transport| |regulation of cellular protein localization| |regulation of transmembrane transport| |regulation of ion transport| |regulation of cellular localization| |positive regulation of transport| |regulation of protein localization| |identical protein binding| |cell-cell signaling| |cell development| |intracellular signal transduction| |tissue development| |positive regulation of molecular function| |regulation of transport| |system process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp49|NFN1 0.1μM R01 exp49]]|-1.98| |[[:results:exp8|Brefeldin A 0.02μM R00 exp8]]|-1.93| |[[:results:exp436|Dynasore 7μM R08 exp436]]|1.78| |[[:results:exp405|Tenofovir 10μM R07 exp405]]|1.82| |[[:results:exp262|Alda-1 10μM R06 exp262]]|1.85| |[[:results:exp535|Trimetrexate 0.03μM R08 exp535]]|2.1| No correlation found to any other genes in chemogenomics.
