DCP2 | m7GpppN-mRNA hydrolase; Decapping metalloenzyme that catalyzes the cleavage of the cap structure on mRNAs. Removes the 7- methyl guanine cap structure from mRNA molecules, yielding a 5'- phosphorylated mRNA fragment and 7m-GDP. Necessary for the degradation of mRNAs, both in normal mRNA turnover and in nonsense- mediated mRNA decay. Plays a role in replication- dependent histone mRNA degradation. Has higher activity towards mRNAs that lack a poly(A) tail. Has no activity towards a cap structure lacking an RNA moiety. The presence of a N(6)-methyladenosine methylation at the second tran [...] (420 aa) | ||||
RHOF | Rho-related GTP-binding protein RhoF; Plasma membrane-associated small GTPase which cycles between an active GTP-bound and an inactive GDP-bound state. Causes the formation of thin, actin-rich surface projections called filopodia. Functions cooperatively with CDC42 and Rac to generate additional structures, increasing the diversity of actin-based morphology. (211 aa) |
