Wikify date April 2010 Protein subfamily is a level of protein classification, especially protein 3D structures. It is under protein family. Protein family in SCOP Structural Classification of Proteins means the members are all related evolutionarily and they share very similar structures with functional similarities. Protein subfamily is when the family members share the same interaction interfaces and interaction partners. This more strict criterion forces that all the subfamily members have to share functionally related.

The protein is expressed in Escherichia coli as a mechanism for regulating the gene copy number s of plasmid s. The Rop protein s structure has been solved to high resolution. ref Banner Due to its small size and known structure, Rop has been used in protein design work to rearrange its helical topology and reengineer its loop regions. ref Kresse In general, the four helix bundle has been extensively used in de novo protein design work as a simple model to understand the relationship between amino acid sequence and structure.

The M1 protein is a matrix protein of the influenza virus . It forms a coat inside the viral envelope . The M1 protein binds to the viral ribonucleic acid RNA . The binding is not specific to any RNA sequence, and is performed via a peptide sequence rich in base chemistry basic amino acid s. It also has multiple regulatory functions, performed by interaction with the components of the host cell. The mechanisms regulated include a role in the export of the viral ribonucleoprotein s from the host cell nucleus , inhibition of viral transcription genetics transcription , and a role in the virus assembly and budding . The protein was found to undergo phosphorylation in the host cell. The M1 protein forms a layer under the patches of host cell membrane that are rich with the viral hemagglutinin , neuraminidase and M2 protein M2 transmembrane protein s, and facilitates budding of the mature viruses.

C4BP has a octopus like structure with a central stalk and seven branching alpha chains. The main form of C4BP in human blood is composed of 7 identical alpha chains and one unique beta chain, which in turn binds anticoagulant, vitamin K dependent protein S.
