ID ACTB_PONPY Reviewed; 375 AA. AC Q5R6G0; Q5R582; DT 26-JUN-2007, integrated into UniProtKB/Swiss-Prot. DT 21-DEC-2004, sequence version 1. DT 24-JUL-2007, entry version 16. DE Actin, cytoplasmic 1 (Beta-actin). GN Name=ACTB; OS Pongo pygmaeus (Orangutan). OC Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; OC Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; OC Catarrhini; Hominidae; Pongo. OX NCBI_TaxID=9600; 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. Found in a complex with XPO6, CC Ran, ACTB and PFN1. Interacts with XPO6 (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm (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.
