ID ACTB_PONAB Reviewed; 375 AA. AC Q5R6G0; Q5R582; DT 26-JUN-2007, integrated into UniProtKB/Swiss-Prot. DT 21-DEC-2004, sequence version 1. DT 25-NOV-2008, entry version 24. DE RecName: Full=Actin, cytoplasmic 1; DE AltName: Full=Beta-actin; GN Name=ACTB; OS Pongo abelii (Sumatran orangutan).

OX NCBI_TaxID=9601; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE MRNA]. RC TISSUE=Brain cortex; RG The German cDNA consortium; RL Submitted (NOV-2004) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Actins are highly conserved proteins that are involved CC in various types of cell motility and are ubiquitously expressed CC in all eukaryotic cells (By similarity). CC -!- SUBUNIT: Polymerization of globular actin (G-actin) leads to a CC structural filament (F-actin) in the form of a two-stranded helix. CC Each actin can bind to 4 others. Component of the BAF complex, CC which includes at least actin (ACTB), ARID1A, ARID1B/BAF250, CC SMARCA2, SMARCA4/BRG1, ACTL6A/BAF53, ACTL6B/BAF53B, SMARCE1/BAF57 CC SMARCC1/BAF155, SMARCC2/BAF170, SMARCB1/SNF5/INI1, and one or more CC of SMARCD1/BAF60A, SMARCD2/BAF60B, or SMARCD3/BAF60C. In muscle CC cells, the BAF complex also contains DPF3. Found in a complex with CC XPO6, Ran, ACTB and PFN1. Component of a complex composed at least CC of ACTB, AP2M1, AP2A1, AP2A2, MEGF10 and VIM. Interacts with XPO6 CC (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton (By similarity). CC -!- MISCELLANEOUS: In vertebrates 3 main groups of actin isoforms, CC alpha, beta and gamma have been identified. The alpha actins are CC found in muscle tissues and are a major constituent of the CC contractile apparatus. The beta and gamma actins coexist in most CC cell types as components of the cytoskeleton and as mediators of CC internal cell motility (By similarity). CC -!- SIMILARITY: Belongs to the actin family.
