Protein
Guanine nucleotide exchange factor MSS4
Function
Guanine-nucleotide-releasing protein that acts on members of the SEC4/YPT1/RAB subfamily. Stimulates GDP release from both YPT1 and RAB3A, but is less active on these proteins than on the SEC4 protein. Might play a general role in vesicular transport (By similarity).
Similarity
Belongs to the DSS4/MSS4 family.
