PROTEOMICS
alternative splicing (2-3/gene) and multiple different types of
post-translational modification, each of which may go to
differing degrees of completion, make the proteome
MUCH larger than the transcriptome (10X-100X)
protein levels and transcript expression not perfectly
correlated
our ability to predict genes and transcripts, let alone proteins,
from primary genomic sequence is only fair.
proteome informatics problems:
a. protein identification
b.  pattern analysis--similar to array analysis
