yeah. and collagenases, the gelatinases, the stromelysins, and the membrane type MMPs are the groups included in MMPs

methylation of guanosin cap on 5' end occurs in where? nucleus or cytosol?
09-13-2007, 04:07 PM
guanosine cap and poly A tail both occur in nucleus. They prevent degradation by nucleases and help in transport from nucleus to cytoplasm.
correct me if i am wrong

Originally I thought the same way as you did, but UW gives a different point.
capping on 5' end include 2 stages: 1. in Nucleus: addition of guanine triphosphate catalyzed by gluanyltranferase 2.in cytosol: methylation of guanosine cap, protect mRNA from degradation by cellular exonucleases. thanks

good morning...
page 92 Collagen synthesis and structure 3. Glycosylation(Golgi) UW says glycosylation happens in RER? what is your opinion?
09-14-2007, 09:42 AM
Actually, kaplan is on UW's said on this point. Procollagen is transferred to Golgi for more modification after glycosylation in RER. page 59 bio

anyone can briefly explain the vesicular trafficking proteins? such as COP1, COP2.

True or false: catalse positivity is necessary but not sufficient for opportunistic infectivity in CGD. |
