Beta-actin (PS1TP5-binding protein 1), also known as ACTB, PS1TP5BP1. Entrez Protein NP_001092. It is one of six different actin proteins. Actin, a ubiquitous eukaryotic protein, is the major component of the cytoskeleton.Actins are highly conserved proteins that are involved in various types of cell motility, structure, and integrity. Actin is ubiquitously expressed in all eukaryotic cells. This actin is a major constituent of the contractile apparatus and one of the two nonmuscle cytoskeletal actins.
Actin is a highly conserved protein that polymerizes to produce filaments that form cross-linked networks in the cytoplasm of cells (PubMed:29581253). Actin exists in both monomeric (G-actin) and polymeric (F-actin) forms, both forms playing key functions, such as cell motility and contraction (PubMed:29581253). In addition to their role in the cytoplasmic cytoskeleton, G- and F-actin also localize in the nucleus, and regulate gene transcription and motility and repair of damaged DNA (PubMed:29925947).
Oxidation of Met-44 and Met-47 by MICALs (MICAL1, MICAL2 or MICAL3) to form methionine sulfoxide promotes actin filament depolymerization. MICAL1 and MICAL2 produce the (R)-S-oxide form. The (R)-S-oxide form is reverted by MSRB1 and MSRB2, which promote actin repolymerization.
Monomethylation at Lys-84 (K84me1) regulates actin-myosin interaction and actomyosin-dependent processes (PubMed:23673617). Demethylation by ALKBH4 is required for maintaining actomyosin dynamics supporting normal cleavage furrow ingression during cytokinesis and cell migration (PubMed:23673617).
Methylated at His-73 by SETD3 (PubMed:30526847, PubMed:30626964, PubMed:30785395). Methylation at His-73 is required for smooth muscle contraction of the laboring uterus during delivery (By similarity).
N-terminal acetylation by NAA80 affects actin filament depolymerization and elongation, including elongation driven by formins (PubMed:29581253). In contrast, filament nucleation by the Arp2/3 complex is not affected (PubMed:29581253).
(Microbial infection) Monomeric actin is cross-linked by V.cholerae toxins RtxA and VgrG1 in case of infection: bacterial toxins mediate the cross-link between Lys-50 of one monomer and Glu-270 of another actin monomer, resulting in formation of highly toxic actin oligomers that cause cell rounding (PubMed:19015515). The toxin can be highly efficient at very low concentrations by acting on formin homology family proteins: toxic actin oligomers bind with high affinity to formins and adversely affect both nucleation and elongation abilities of formins, causing their potent inhibition in both profilin-dependent and independent manners (PubMed:26228148).
Note: Localized in cytoplasmic mRNP granules containing untranslated mRNAs.
Polymerization of globular actin (G-actin) leads to a structural filament (F-actin) in the form of a two-stranded helix (PubMed:28604741, PubMed:16685646). Each actin can bind to 4 others (PubMed:28604741, PubMed:16685646). Identified in a IGF2BP1-dependent mRNP granule complex containing untranslated mRNAs (PubMed:17289661). Component of the BAF complex, which includes at least actin (ACTB), ARID1A, ARID1B/BAF250, SMARCA2, SMARCA4/BRG1, ACTL6A/BAF53, ACTL6B/BAF53B, SMARCE1/BAF57 SMARCC1/BAF155, SMARCC2/BAF170, SMARCB1/SNF5/INI1, and one or more of SMARCD1/BAF60A, SMARCD2/BAF60B, or SMARCD3/BAF60C (PubMed:18765789). In muscle cells, the BAF complex also contains DPF3 (PubMed:18765789). Found in a complex with XPO6, Ran, ACTB and PFN1 (PubMed:14592989). Interacts with XPO6 and EMD (PubMed:15328537). Interacts with ERBB2 (PubMed:21555369). Interacts with GCSAM (PubMed:17823310). Interacts with TBC1D21 (By similarity). Interacts with CPNE1 (via VWFA domain) and CPNE4 (via VWFA domain) (By similarity). Interacts with DHX9 (via C-terminus); this interaction is direct and mediates the attachment to nuclear ribonucleoprotein complexes (PubMed:11687588). Interacts with FAM107A (PubMed:21969592, PubMed:28604741).

Tips: For phospho antibody, we provide phospho peptide（0.5mg) and non-phospho peptide(0.5mg).
Blocking peptides are peptides that bind specifically to the target antibody and block antibody binding. These peptide usually contains the epitope recognized by the antibody. Antibodies bound to the blocking peptide no longer bind to the epitope on the target protein. This mechanism is useful when non-specific binding is an issue, for example, in Western blotting (immunoblot) and immunohistochemistry (IHC). By comparing the staining from the blocked antibody versus the antibody alone, one can see which staining is specific; Specific binding will be absent from the western blot or immunostaining performed with the neutralized antibody.
