LIMD1 Polyclonal antibody

LIMD1 is a member of the Ajuba family of LIM domain-containing proteins, these kinds of proteins have been shown to play a role in intracellular signaling, transcriptional regulation and cellular differentiation, proliferation and migration (PMID:17174104). LIMD1 predominantly localizes to the cytoplasm especially in the E-cadherin cell-cell adhesive junction, yet also translocates to the nucleus when functions as an RB corepressor (PMID:19060205). And LIMD1 acts as a scaffolding protein to form a PHD-LIMD1-VHL axis, facilitating HIF1α ubiquitination and degradation by the proteasome (PMID:22800800). LIMD1 specifically interacts with retinoblastoma protein (pRB), inhibits E2F-mediated transcription, and suppresses the expression of the majority of genes with E2F1-responsive elements. As a tumor suppressor, LIMD1 blocks tumor growth in vitro and in vivo, and is frequently down-regulated in human lung tumors (PMID:15542589), and it also be detected in normal and breast cancer tissues. LIMD1 protein exists several phosphorylation sites, which may affect its theoretical molecular weight when tested. Proteintech's 28106-1-AP antibody was generated by 133 amino acids, it could recognize the full-length protein in applications.
