What pLDDT means and how to read it

Function

Cytoskeletal protein involved in actin-membrane attachment at sites of cell adhesion to the extracellular matrix (focal adhesion). Recruits other proteins such as TRIM15 to focal adhesion

Subunit structure

Interacts in vitro with VCL/vinculin as well as to the SH3 domain of SRC and, when tyrosine phosphorylated, to the SH2 domain of CRK (PubMed:7534286). Interacts with GIT1 (PubMed:10938112). Interacts with NUDT16L1/SDOS (By similarity). Interacts with PTK2/FAK1 (PubMed:14527389). Interacts with PTK2B/PYK2 (PubMed:19358827). Interacts with ASAP2 (PubMed:10749932). Interacts with unphosphorylated…
