What pLDDT means and how to read it

Function

Adapter protein that links structural and signaling protein complexes positioned to guide microtubule and actin cytoskeleton dynamics during cell morphogenesis (PubMed:22084092, PubMed:24120883). At focal adhesions (FAs) rims, organizes cortical microtubule stabilizing complexes (CMSCs) and directly interacts with major FA component TLN1, forming macromolecular assemblies positioned to control microtubule-actin crosstalk at the cell edge (PubMed:24120883, PubMed:27410476). Recruits KIF21A in CMSCs at axonal growth cones and regulates axon guidance by suppressing microtubule growth without inducing microtubule disassembly once it reaches the cell cortex (PubMed:24120883). Interacts with…

Subunit structure

Part of a cortical microtubule stabilization complex (CMSC) composed of KANK1, PPFIA1, PPFIBP1, ERC1/ELKS, PHLDB2/LL5beta, CLASPs, KIF21A and possibly additional interactors; within CMSCs KANK1 and PHLDB2/LL5beta seem to be the core components for recruiting microtubule-binding proteins KIF21A and CLASPs, whereas PPFIA1, PPFIBP1 and ERC1/ELKS serve as scaffolds for protein clustering…
