ABSTRACT
|
|
|
| |
|
The interaction between the cytoskeletal proteins talin and vinculin plays a key
role in integrin-mediated cell adhesion and migration. Three vinculin binding
sites (VBS1-3) have previously been identified in the talin rod using a yeast
two-hybrid assay. To extend these studies, we spot-synthesized a series of
peptides spanning all the alpha-helical regions predicted for the talin rod and
identified eight additional VBSs, two of which overlap key functional regions of
the rod, including the integrin binding site and C-terminal actin binding site.
The talin VBS alpha-helices bind to a hydrophobic cleft in the N-terminal
vinculin Vd1 domain. We have defined the specificity of this interaction by
spot-synthesizing a series of 25-mer talin VBS1 peptides containing
substitutions with all the commonly occurring amino acids. The consensus for
recognition is LXXAAXXVAXX- VXXLIXXA with distinct classes of hydrophobic side
chains at positions 1, 4, 5, 8, 9, 12, 15, and 16 required for vinculin binding.
Positions 1, 8, 12, 15, and 16 require an aliphatic residue and will not
tolerate alanine, whereas positions 4, 5, and 9 are less restrictive. These
preferences are common to all 11 VBS sequences with a minor variation occurring
in one case. A crystal structure of this variant VBS peptide in complex with the
vinculin Vd1 domain reveals a subtly different mode of vinculin binding.

Figure 2.
FIGURE 2. Relative distribution of the VBS peptides among
the 63 predicted -helices which make up
the talin rod. Vinculin binding helices are shown in blue and
non-binders in gray. VBS1-3 (peptides 4, 12, and 46) were
previously mapped using a yeast two-hybrid assay (21). The black
line indicates the position of an integrin binding site
(residues 1984-2113) (18), and the red line the C-terminal actin
binding site (residues 2295-2541) (19, 20).

FIGURE 5. Analysis of talin VBS rule violations. A,
alignment of talin peptides with sequences that do not conform
with the position-specific preferences for vinculin binding
defined in Fig. 4. Residues on a gray background align with the
highly buried (>75%) hydrophobic side chains from the talin
VBS1·vinculin Vd1 complex crystal structure. Residues
that would be predicted to knock out binding of VBS1 to vinculin
(Fig. 4) are indicated in white. Included are weak/borderline
vinculin binding VBS peptides and also two non-binding peptides
5 and 21, which appear to conform to the VBS consensus. All of
the strong binders conform to the rules except peptides 11 and
12 (VBS2). From the weak binders, only peptides 36 and 60 have
no rule violations. B, conversion of VBS2 (peptide 12) into a
strong vinculin binder by substituting residues from VBS1
(peptide 4). Note the negative influence of Thr and Met in
positions 12 and 15.

only a partial list as not all journals are covered by
either method. However, we are continually building up the citation data
so more and more references will be included with time.
