Zinedin, SG2NA, and striatin are calmodulin-binding, WD repeat proteins principally expressed in the brain.
Striatin is an intracellular protein characterized by four protein-protein interaction domains, a caveolin-binding motif, a coiled-coil structure, a calmodulin-binding domain, and a WD repeat domain, suggesting that it is a signaling or a scaffold protein. Down-regulation of striatin, which is expressed in a few subsets of neurons, impairs the growth of dendrites as well as rat locomotor activi...
متن کاملMetacercarial proteins interacting with WD40-repeat protein of Clonorchis sinensis.
The WD40-repeat proteins serve as a platform coordinating partner proteins and are involved in a range of regulatory cellular functions. A WD40-repeat protein (CsWD1) of Clonorchis sinensis previously cloned is expressed stage-specifically in the tegumental syncytium of C. sinensis metacercariae. In the present study, interacting proteins with the CsWD1 protein was purified by immunoprecipitati...

780 amino acids (aa), 86.13 KDa (isoform I) and 731 amino acids, 80.76 KDa (isoform II). Striatin contains a high number of domains mediating protein-protein interactions. Domains: aa 55-63 : Caveolin-binding; aa 53-120 : Coiled-coil; aa 149-166 : Calmodulin-binding; aa 461-500 : WD 1; aa 514-553 : WD 2; aa 567-606 : WD 3; aa 662-701 : WD 4; aa 704-743 : WD 5; aa 750-779 : WD 6 (30 aa only) (Is...
متن کاملWDSPdb: a database for WD40-repeat proteins
WD40-repeat proteins, as one of the largest protein families, often serve as platforms to assemble functional complexes through the hotspot residues on their domain surfaces, and thus play vital roles in many biological processes. Consequently, it is highly required for researchers who study WD40 proteins and protein-protein interactions to obtain structural information of WD40 domains. Systema...
متن کاملPoxvirus ankyrin repeat proteins are a unique class of F-box proteins that associate with cellular SCF1 ubiquitin ligase complexes.
F-box proteins direct the degradation of an extensive range of proteins via the ubiquitin-proteasome system. Members of this large family of proteins are typically bipartite. They recruit specific substrates through a substrate-binding domain and, via the F-box, link these to core components of a major class of ubiquitin ligases (SCF1). F-box proteins thus determine the specificity of SCF1-medi...
