Abstract The SEC7 domain was named after the first protein found to contain such a region [PubMed3042778]. It has been shown to be linked with guanine nucleotide exchange function [PubMed9072969, PubMed9442017]. The 3D structure of the domain displays several alpha-helices [PubMed9653114]. It was found to be associated with other domains involved in guanine nucleotide exchange (e.g., CDC25, Dbl) in mammalian factors [PubMed9868368].

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 6 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a Sec7 domain domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 6 hidden Markov models representing the Sec7 domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
