C6

C6
SMART accession number:SM01048
Description: This domain of unknown function is found in the C. elegans protein Q19522. It is presumed to be an extracellular domain. The C6 domain contains six conserved cysteine residues in most copies of the domain. However some copies of the domain are missing cysteine residues 1 and 3 suggesting that these form a disulphide bridge.
Interpro abstract (IPR002601):

This domain of unknown function is found at the C terminus in a number of Caenorhabditis elegans and briggsae proteins. It may be an extracellular domain. Most copies of the domain contain six conserved cysteine residues.
