| - | [[Vinculin|Vinculins]] (VCLs) are involved in adhesion by linking integrin molecules to the actin cytoskeleton. Its head domain (Vd1) can bind to [[Talin|talin]] or to [[Actinin|alpha-actinin]] at their respective VCL Binding Sites (VBS). | + | == Function == |
| - | + | [[Vinculin|Vinculins]] (VCLs) are involved in adhesion by linking integrin molecules to the actin cytoskeleton. Its head domain (Vd1) can bind to [[Talin|talin]] or to [[Actinin|alpha-actinin]] at their respective VCL Binding Sites (VBS)<ref>PMID:11152287</ref>. The protein raver1 RNA Recognition Motif (RRM) forms a complex with VCL or m-VCL. '''Metavinculin''' (m-VCL) is a splice version of VCL containing an extra ca. 70 amino acids in the C-terminal domain. | |
