Antibody Host Species: Rabbit
Antibody Immunogen Source: Human Abl2 (Arg) sequence peptide Cat. No.: PE-04AII85
Antibody Immunogen Sequence: GDT(pY)TAH(bA)C
Antibody Immunogen Description: Corresponds to amino acid residues G436 to H442; in the protein kinase catalytic domain activation T loop region between subdomains VII and VIII. Y439 phosphorylation is predicted to be stimulatory for phosphotransferase activity. It is the major site of phosphorylation of Abl2 with ≥1673 reports by mass spectrometry in PhosphoSitePlus. Arg is known to be phosphorylated at this site in vitro by Arg (Abl2), and PDGFRB.
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.This antibody was also subject to negative purification over phosphotyrosine-agarose.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: Arg (Abl2) is a protein-tyrosine kinase of the TK group and Abl family. It features SH3 and SH2 domains, a protein- tyrosine kinase domain, and a nuclear localization domain. It shares many functions with Abl1, which includes cytoskeleton remodelling through phosphorylation of enzymes responsible for cytoskeleton rearrangements for signalling, adhesion, and movement as well as microtuble subunits, TUBA1 and TUBB. It also contains F-actin binding region to bundle and regulate actin cytoskeletal structure. While primarily cytoplasmic (lacks the nuclear localization signal of ABL1), it localizes to F-actin-rich areas like focal adhesions, lamellipodia, and dendritic spines. It possesses autocatalytic activity and the ability to phosphorylate its inhibitor ABI1 to regulate itself. It phosphorylates proteins like CTTN (cortactin), CRK, and ARHGAP35 to modulate cell adhesion and motility. Arg gene expression is found in both normal and tumour cells, it is often found as a fusion gene with ETV6 in acute non lymphocytic leukemias. However, the broad distribution of point mutations seen in various cancers, including about a third within the kinase catalytic domain, indicate that these mutations are likely to be silent or result in loss of function. Arg has also been reported to promote breast tumour cell invasion and dissemination, but attenuates the growth of breast tumours. This indicates that wild-type Arg may as a tumour suppressor protein. Phosphorylation of Tyr-261 reduces ubiquitination and protein degradation. Arg is activated by autophosphorylation as well as by Src-family kinase-mediated phosphorylation. It is also activated by RIN1 binding to the SH2 and SH3 domains. Arg is also involved in neuronal development (dendrite arbor stability) and is frequently implicated in translocations in leukemia.
