Gene or Protein database sites - (Feb/01/2012 )

To get a quick view about a gene or protein, use OMIM in the ncbi site

http://www.ncbi.nlm.nih.gov/omim

and BioGPS

How about www.xpasy.org for proteins?

http://www.proteinatlas.org/

find protein expression profiles based on immunohistochemistry

The Phosphosite Database is great for post-translational modification and links to all of the other standard databases for each protein:
