== Function ==
[[http://www.uniprot.org/uniprot/PARVA_HUMAN PARVA_HUMAN]] Plays a role in sarcomere organization and in smooth muscle cell contraction. Required for normal development of the embryonic cardiovascular system, and for normal septation of the heart outflow tract. Plays a role in sprouting angiogenesis and is required for normal adhesion of vascular smooth muscle cells to endothelial cells during blood vessel development (By similarity). Plays a role in the reorganization of the actin cytoskeleton, formation of lamellipodia and ciliogenesis. Plays a role in the establishement of cell polarity, cell adhesion, cell spreading, and directed cell migration.<ref>PMID:11331308</ref> <ref>PMID:11134073</ref> <ref>PMID:15284246</ref> <ref>PMID:20393563</ref>

== Publication Abstract from PubMed ==
The adaptor protein paxillin contains five conserved leucine-rich (LD) motifs that interact with a variety of focal adhesion proteins, such as alpha-parvin. Here, we report the first crystal structure of the C-terminal calponin homology domain (CH(C)) of alpha-parvin at 1.05 A resolution and show that it is able to bind all the LD motifs, with some selectivity for LD1, LD2, and LD4. Cocrystal structures with these LD motifs reveal the molecular details of their interactions with a common binding site on alpha-parvin-CH(C), which is located at the rim of the canonical fold and includes part of the inter-CH domain linker. Surprisingly, this binding site can accommodate LD motifs in two antiparallel orientations. Taken together, these results reveal an unusual degree of binding degeneracy in the paxillin/alpha-parvin system that may facilitate the assembly of dynamic signaling complexes in the cell.

Structural analysis of the interactions between paxillin LD motifs and alpha-parvin.,Lorenz S, Vakonakis I, Lowe ED, Campbell ID, Noble ME, Hoellerer MK Structure. 2008 Oct 8;16(10):1521-31. PMID:18940607<ref>PMID:18940607</ref>
