Leupaxin Expression Is Dispensable for B Cell Immune Responses.
Title: Leupaxin Expression Is Dispensable for B Cell Immune Responses.
The kindlin-3 not only activates and clusters integrins into podosomes but also regulates their lifetime by recruiting leupaxin, which controls PTP-PEST activity and thereby paxillin phosphorylation and downstream signaling.
Title: A kindlin-3-leupaxin-paxillin signaling pathway regulates podosome stability.
leupaxin functions as a paxillin counterpart that potently suppresses the tyrosine phosphorylation of paxillin during integrin signaling.
Title: LIM domain-containing adaptor, leupaxin, localizes in focal adhesion and suppresses the integrin-induced tyrosine phosphorylation of paxillin.
Leupaxin is enriched in mouse vascular smooth muscle and its expression is dynamically regulated during development.
Title: The LIM protein leupaxin is enriched in smooth muscle and functions as an serum response factor cofactor to induce smooth muscle cell gene transcription.
Leupaxin plays an inhibitory role in BCR signaling and B cell function.
Title: Leupaxin negatively regulates B cell receptor signaling.
leupaxin may be a critical nucleating component of the osteoclast podosomal signaling complex
Title: Leupaxin is a critical adaptor protein in the adhesion zone of the osteoclast.
Association of the scaffold protein LPXN with Src adds further complexity to the organization of the podosomal signaling complex in osteoclasts.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
