 Gene3D can be queried with most recognised identifiers  (e.g. uniprot ID's) along with any gene names provided by these resources. If your query returns more than one sequence, then you will be able to choose the appropriate one from the lists provided. Here we want to find out about VAV1 in human.

 The main track is the top one, displaying the resolved MDA (the coloured blobs) and all the matches from the various HMM profiles (dotted brackets). Matches from the same superfamily are the same colour, and you can find the E-value by mousing over. Hopefully this image demonstrates two things: (1) The complexity involved in precisely defining domain boundaries (2) The robustness of DomainFinder3 - the in-house algorithm for match selection (paper under review). The main track is the top one, displaying the resolved MDA (the coloured blobs) and all the matches from the various HMM profiles (dotted brackets).
