Transcriptional coactivator for androgen receptor (AR) and serum response factor (SRF). Contributes to the regulation of cell adhesion, spreading and cell migration and acts as a negative regulator in integrin-mediated cell adhesion events. Suppresses the integrin-induced tyrosine phosphorylation of paxillin (PXN). May play a critical role as an adapter protein in the formation of the adhesion zone in osteoclasts. Negatively regulates B-cell antigen receptor (BCR) signaling.

LPXN may facilitate bladder cancer progression by upregulating the expression of S100P via PI3K/AKT pathway. These results provide a novel insight into the role of LPXN in tumorigenesis and progression of bladder cancer and potential therapeutic target of bladder cancer. PMID: 29975926
this is the first demonstration of a role for the leupaxin in the regulation of hepatocellular carcinoma progression, at least in part, by enhancing beta-catenin transcription activity. PMID: 26361959

leupaxin could serve as a potential progression marker for a subset of PCa and may represent a novel coactivator of the androgen receptor PMID: 18451096
Leupaxin is enriched in vascular smooth nuscle. It undergoes cytoplasmic/nuclear shuttling & functions as an serum response factor cofactor. It associates with CArG-containing regions. Its ectopic expression induces smooth muscle marker gene expression. PMID: 18497331
LPXN, a member of the paxillin superfamily, is fused to RUNX1 in an acute myeloid leukemia patient with a t(11;21)(q12;q22) translocation. PMID: 19760607

亞細胞定位:
Cytoplasm. Cell junction, focal adhesion. Nucleus. Cytoplasm, perinuclear region. Cell projection, podosome. Cell membrane. Note=Shuttles between the cytoplasm and nucleus. Recruited to the cell membrane following B-cell antigen receptor (BCR) cross-linking in B-cells. Enhanced focal adhesion kinase activity (PTK2/FAK) attenuates its nuclear accumulation and limits its ability to enhance serum response factor (SRF)-dependent gene transcription. Targeting to focal adhesions is essential for its tyrosine phosphorylation in response to bombesin.
