These are small monomeric proteins homologous to Ras (protein).

Despite these achievements, detection and interpretation of relationships between homologous proteins that have limited sequence similarity remains a major challenge.

Since humans do not have a homologous protein, these enzymes are possible new targets for drug therapies against these diseases.

There must have been a rudimentary prokaryotic homologous protein that was capable of similar self-assembly.

Other homologous proteins have been found in Clostridium spiroforme.

In species studied to date, host defense appears to be mediated by homologous proteins.

Its general usage is to identify homologous protein or nucleotide sequences.

Alignment of homologous proteins can be used to calculate conservation metric for a motif.

When a homologous protein is found, the proteins are considered to have a common ancestor and their functions are inferred as being similar.

He also created the "ladder model" that could be applied to electrophoresis studies where homologous proteins differ by whole units of charge.
