proteasomes/MCPs

[suter at VAX.MPIZ-KOELN.MPG.DBP.DE]

dear colleagues,

during a race amplification of plant mRNA, i have stumbled on yet another
gene: this time a sequence with large homologies to proteasome- or "multi-
catalytic proteinases" (MCP)- subunits.
I have been gone through the literature, came up with some interesting
articles, but have still some questions:
1. any news about the functions of MCP ?
2. are MCPs associated with small RNAs (are they snurps)?
3. are they single copy genes ?
4. do you know of other PLANT MCP subunits that were cloned ?
5. do you know of a recent publication (or even review) which discusses
these points ?

I would be gratefull for any useful pointers!

ciao, clemens
