  2. Data suggest that the first LD motif (LD1; leucine-rich motif) of paxillin binds to the CCHD (C-terminal region of Cas family homology domain) of p130Cas/Bcar1 (in a 1:1 stoichiometry with Kd approximately 4.2 uM); p130Cas/Bcar1 CCHD is stabilized by forming complex with paxillin LD1; these studies utilized chicken paxillin and mouse p130Cas/Bcar1.

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.
