Antibody Target Type: Phosphosite-specific
Antibody Phosphosite: Y53
Protein UniProt: P60709
Protein SigNET: ACTB
Antibody Type: Polyclonal
Antibody Host Species: Rabbit
Antibody Immunogen Source: Human ACTB (Beta-actin) sequence peptide Cat. No.: PE-04AIB95
Antibody Immunogen Sequence: KDS(pY)VGD(bA)C
Antibody Immunogen Description: Corresponds to amino acid residues K50 to D56; in the Actin domain. The effect of Y53 phosphorylation is unclear. This is one of the major in vivo phosphorylation sites in actin from mass spectrometry studies (≥1,087 reports recorded in PhosphoSitePlus).
Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: Actins are highly conserved proteins that are involved in various types of cell motility. They are a family of globular multi-functional proteins that form microfilaments in the cytoskeleton, and the thin filaments in muscle fibrils. It can be present as either a free monomer called G-actin (globular) or as part of a linear polymer microfilament called F-actin (filamentous), both of which are essential for such important cellular functions as the mobility and contraction of cells during cell division. It is found in essentially all eukaryotic cells, where it may be present at a concentration of over 100 μM. ACTB (Actin, cytoplasmic 1; beta-actin) is a 42 kDa protein that is highly conserved, and ubiquitously expressed, and essential for maintaining cell structure, integrity, and motility. Beyond the cytoplasm, beta-actin plays a key role in the nucleus, where it is involved in gene transcription, chromatin remodeling, and repair of damaged DNA. Beta-actin is required for early embryonic development and is critical for the migration and function of cells like neurons and white blood cells. Mutations in the ACTB gene disrupt the actin cytoskeleton, leading to various developmental disorders, including Baraitser-Winter Syndrome, which is a rare disorder affecting brain, eye, and facial development, commonly caused by R196H mutations. Dysregulation of beta-actin is also linked to cancer cell metastasis and immune cell dysfunction. This description may include information annotated by UniProt and/or Google AI.
