Immunohistochemical staining of human prostate with ABL1 polyclonal antibody (Cat # PAB21888) shows cytoplasmic and membranous positivity in glandular cells at 1:50-1:200 dilution.
Immunofluorescence
Immunofluorescent staining of human cell line U-251MG with ABL1 polyclonal antibody (Cat # PAB21888) at 1-4 ug/mL dilution shows positivity in nuclei but not nucleoli.
The ABL1 protooncogene encodes a cytoplasmic and nuclear protein tyrosine kinase that has been implicated in processes of cell differentiation, cell division, cell adhesion, and stress response. Activity of c-Abl protein is negatively regulated by its SH3 domain, and deletion of the SH3 domain turns ABL1 into an oncogene. The t(9;22) translocation results in the head-to-tail fusion of the BCR (MIM:151410) and ABL1 genes present in many cases of chronic myelogeneous leukemia. The DNA-binding activity of the ubiquitously expressed ABL1 tyrosine kinase is regulated by CDC2-mediated phosphorylation, suggesting a cell cycle function for ABL1. The ABL1 gene is expressed as either a 6- or 7-kb mRNA transcript, with alternatively spliced first exons spliced to the common exons 2-11. [provided by RefSeq
