The following text describes a protein:
Function:
High molecular weight cytoskeletal protein concentrated at regions of cell-matrix and cell-cell contacts. Involved in connections of major cytoskeletal structures to the plasma membrane. With KANK1 co-organize the assembly of cortical microtubule stabilizing complexes (CMSCs) positioned to control microtubule-actin crosstalk at focal adhesions (FAs) rims.
Subcellular Localization:
Cell projection, ruffle membrane; Peripheral membrane protein; Cytoplasmic side. Cytoplasm, cytoskeleton. Cell surface. Cell junction, focal adhesion. Note=Colocalizes with LAYN at the membrane ruffles (By similarity). Localized preferentially in focal adhesions than fibrillar adhesions.
Domain:
Consists of an N-terminal FERM domain linked via a short unstructured region to a large flexible C-terminal rod which contains 13 amphipathic helical bundles (R1-R13). The rod begins with a five-helix bundle (R1) followed by three four-helix bundles (R2-R4). These are followed by a series of eight five-helix bundles (R5-R7 and R9-R13) in which the N- and C-termini are positioned at opposite ends of the bundle, creating a linear chain. The four-helix bundle R8 does not disrupt the chain because it is inserted into a loop in the R7 five-helix bundle. The uneven distribution of four- and five-helix bundles creates two distinctly different zones: a compact N-terminal region sensitive to stretch and a linear C-terminal region that is optimal for force transmission.
