PF09431SPIN90/Ldb17, leucine-rich domain (SPIN90_LRD)SPIN90/Ldb17, leucine-rich domainThis is the conserved leucine-rich domain (LRD) within the C-terminal domain of SPIN90 (also known as NCK interacting protein with SH3 domain (NCKIPSD)) from animals, Ldb17 from budding yeasts and Dip1 from fission yeasts [1].

Ldb17 is involved in the regulation of endocytosis in yeast [2]. SPIN90 is an F-actin binding protein that regulates actin polymerization and endocytosis [3]. It associates with and activates the Arp2/3 complex, without requiring a preformed actin filament [2,4,5]. This LRD, within the C-terminal armadillo repeat (ARM) domain of SPIN90, is important for activation of Arp2/3 complex [1].

The human complex consists of seven subunits which include the actin related proteins Arp2 and Arp3, and five others referred to as p41-Arc, p34-Arc, p21-Arc, p20-Arc, and p16-Arc. The precise function of p16-Arc is currently unknown. Its structure consists of a single domain containing a bundle of seven alpha helices [1,2].
