Sequence similarities

Last modified September 9, 2013

This subsection of the ‘General annotation (Comments)’ section provides information about the sequence similarity with other proteins.

This subsection only states sequence similarity, excluding proteins with a related name that may function in the same biological pathway, if they do not share sequence similarities.

The ‘Sequence similarities’ subsection provides 2 types of information: the protein ‘Belongs to’ a family and/or ‘Contains’ a given domain.

‘Belongs to’

The lines ‘Belongs to’ always appear before the lines ‘Contains’. The lines are listed in alphanumerical order.

Examples: Q9C9W3, Q03395, Q15022, P0A6X0, O31792

A protein may belong to two (or even more) different families. In this case, we indicate which part of the protein belongs to a given family.

Example: P40939, O75521


The term ‘domain’ in this context is intended as a structural domain. All domains listed in the ‘Sequence similarities’ subsection of an entry are described in the ‘Sequence annotation (Features)’ in the ‘Domain’, ‘Zinc finger’, ‘Repeat’, ‘Calcium binding’ or ‘DNA binding’ subsections.

Examples: P16581, P78314, P13029, O96006, Q9P6L5, Q9BQL6
