Fig. 1. Paxillin Kozak sequence comparison and paxillin family domain structure. (A) Alignment of the paxillin
and
Kozak nucleotide sequence (Kozak, 1987) from various species. Nucleotides are labeled as follows: G, guanine; C, cytosine; A; adenine; U, uracil; R, purine; aug#, methionine start codon with amino acid position. Shaded residues are most highly conserved and required for ribosome recognition. (B) Avian paxillin
, paxillin
and Hic-5 domain structure. Paxillin
is 559 amino acids and paxillin
is 427 amino acids in length (amino acid numbers in parentheses represent position within paxillin
). Hic-5 Tyr60 residue is a potential Csk binding site (Thomas et al., 1999).
