PROSITE documentation PDOC00923 |
The mouse tubby mutation is the cause of maturity-onset obesity, insulin resistance and sensory deficits. This mutation maps to a gene, tub [1,2], which codes for a protein that belongs to a family which currently consists of the following members:
While the N-terminal part of these protein is not conserved in length nor in the sequence, the C-terminal 250 residues are highly conserved. We therefore selected two regions in the C-terminal part as signature patterns. The second region is located at the C-terminal extremity and contains a penultimate cysteine residue that could be critical to the normal functioning of these proteins.
