membrane/ protein trafficking in the secretory/ biosynthetic and endocytic pathways is mediated by vesicles. vesicle trafficking in eukaryotes is regulated by a class of small monomeric gtpases the rab protein family. rab proteins represent the largest branch of the ras superfamily gtpases, and have been concerned in a variety of intracellular vesicle trafficking and different intracellular sig...
Ras proteins are members of a superfamily of related small GTPases. Some members, such as Ras, are oncogenic. However, other members seem to serve as tumor suppressors, such as Rig and Noey2. We now identify and characterize a novel member of the Ras superfamily, RRP22. Like Ras, RRP22 can be posttranslationally modified by farnesyl. Unlike Ras, RRP22 inhibits cell growth and promotes caspase-i...
Motivation: Protein surface roughness is fractal in nature. Mass, hydrophobicity, polarizability distributions of protein interior are fractal too, as are the distributions of dipole moments, aromatic residues, and many other structural determinants. The open-access server ProtFract, presents a reliable way to obtain numerous fractaldimension and correlation-dimension based results to quantify ...
Small G proteins exist in eukaryotes from yeast to human and constitute the Ras superfamily comprising more than 100 members. This superfamily is structurally classified into five families: the Ras, Rho, Rab, Arf, and Ran families that control a wide variety of cell and biological functions through highly coordinated regulation processes. Increasing evidence has accumulated to identify small G ...
