Function

[CDC24_YEAST] Promotes the exchange of CDC42-bound GDP by GTP. Controls the polarity of calmodulin, and the calcium regulatory process of bud emergence. CDC24 may be involved in the initial selection and organization of the budding site.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.

Publication Abstract from PubMed

The PC motif is evolutionarily conserved together with the PB1 domain, a binding partner of the PC motif-containing protein. For interaction with the PB1 domain, the PC motif-containing region (PCCR) comprising the PC motif and its flanking regions is required. Because the PB1 domain and the PCCR are novel binding modules found in a variety of signaling proteins, their structural and functional characterization is crucial. Bem1p and Cdc24p interact through the PB1-PCCR interaction and regulate cell polarization in budding yeast. Here, we determined a tertiary structure of the PCCR of Cdc24p by NMR. The tertiary structure of the PCCR is similar to that of the PB1 domain of Bem1p, which is classified into a ubiquitin fold. The PC motif portion takes a compact betabetaalpha-fold, presented on the ubiquitin scaffold. Mutational studies indicate that the PB1-PCCR interaction is mainly electrostatic. Based on the structural information, we group the PB1 domains and the PCCRs into a novel family, named the PB1 family. Thus, the PB1 family proteins form a specific dimer with each other.

The PB1 domain and the PC motif-containing region are structurally similar protein binding modules.,Yoshinaga S, Kohjima M, Ogura K, Yokochi M, Takeya R, Ito T, Sumimoto H, Inagaki F EMBO J. 2003 Oct 1;22(19):4888-97. PMID:14517229^[1]
