Secondary Information

Protein Function  Acts as a guanine nucleotide exchange factor (GEF) for Rab5 GTPase. Regulates the ALS2-mediated endosome dynamics.ALS2CL is a novel factor modulating the Rab5-mediated endosome dynamics in the cells.
Biochemical Properties Analysis of the predicted amino acid sequences revealed a high level of sequence similarity throughout the entire region of ALS2CL and the C-terminal portion of the ALS2 proteins, indicating that ALS2CL/Als2cl and ALS2/Als2 were evolutionally conserved genes evolved from a common ancestry of origin.

Significance of PTMs Autophosphorylation at Thr-186, Ser-347, Thr-350, Ser-353, Thr-354 and Ser-357 triggers kinase activity by promoting cyclin and substrate binding upon conformational changes.Phosphorylation at Thr-186 requires the calcium Ca2+ signaling pathway, including CaMK1D and calmodulin.N6-acetylation of Lys-44 promotes kinase activity, whereas acetylation of both Lys-44 and Lys-48 mediated by PCAF/KAT2B and GCN5/KAT2A reduces kinase activity.
Additional Comments ALS2 may implicate in the vesicle/membrane dynamics in the cells through the activation of Rab5.
