Organism
Aspergillus clavatus (strain ATCC 1007 / CBS 513.65 / DSM 816 / NCTC 3887 / NRRL 1)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Type-I myosin implicated in the organization of the actin cytoskeleton. Required for proper actin cytoskeleton polarization. At the cell cortex, assembles in patch-like structures together with proteins from the actin-polymerizing machinery and promotes actin assembly. Functions as actin nucleation-promoting factor (NPF) for the Arp2/3 complex. Plays an important role in polarized growth, spore germination, hyphal morphogenesis, and septal wall formation (By similarity).By similarity

Domaini

The myosin motor domain displays actin-stimulated ATPase activity and generates a mechanochemical force.By similarity
The tail domain participates in molecular interactions that specify the role of the motor domain (By similarity). It is composed of several tail homology (TH) domains, namely a putative phospholipid-binding myosin tail domain (also named TH1), an Ala- and Pro-rich domain (TH2), followed by an SH3 domain and a C-terminal acidic domain (TH3).By similarity
