Background Information

PBXIP1 (pre-B-cell leukemia transcription factor-interacting protein 1), also known as HPIP (hematopoietic PBX-interacting protein), is a regulator of pre-B-cell leukemia transcription factors (BPXs) function. PBXIP1 is a nucleo-cytoplasmic shuttling protein, mainly localized in the cytosol and in small amounts in the nucleus (PMID: 10825160). It interacts with PBX1 as well as PBX2 and PBX3. PBXIP1 inhibits the ability of PBX-HOX heterodimers to bind to target sequences and strongly inhibits the transactivation activity of E2A-PBX. PBXIP1 is also reported to be a microtubule-binding protein, which regulates estrogen receptor functions and plays a role in cancer development and progression (PMID: 17043237; 18302941; 23321675). The predicted PBXIP1 protein has a calculated molecular mass of 81 kDa. This polyclonal antibody raised against 1-300aa of human PBXIP1 recognizes endogenous PBXIP1 with an apparent molecular weight of 95-100 kDa. The slow migration of PBXIP1 possibly results from either post-translational modifications or intrinsic SDS-resistant folding of the protein (PMID: 10825160; 17043237).
