.clusters() gives you a VertexClustering object:

https://pythonhosted.org/python-igraph/igraph.clustering.VertexClustering-class.html

You can call its .giant() method to get the largest component and then you can 
simply retrieve the vertex names from there:

cl = g.clusters()
largest_component = g.giant()
print largest_component.vs[“name”]

(This assumes that the protein names are stored in a vertex attribute named 
“name”)
