Figure 4.
Structure of the abLIM polypeptides. (a) Diagrams of the protein structures of three abLIM isoforms. Features indicated in the protein sequence are: VILLIN, homology to both dematin and the villin headpiece; DEMATIN-undefined, homology to the “undefined” domain of dematin; LIM1–4, LIM motifs. Together, the VILLIN + DEMATIN-undefined regions make up the dematin-like region of abLIM. (b) Sequence comparison of the four LIM domains from paxillin and abLIM protein. The LIM consensus sequence is indicated at the bottom of the figure. Conserved C/H/D residues within the LIM backbone are indicated by dark shading, conserved hydrophobic residues are indicated by light shading, and residues conserved only within the four abLIM protein LIM domains are indicated by unshaded boxes.
