A more recent theory suggests that aquagenic keratoderma in CF patients is due to dysfunction of transient receptor potential cation channel subfamily V member 4, a protein channel that activates a signal cascade to reduce cell volume swelling from osmosis in unaffected patients.
The structure modeling here showed that the deletion destabilized the structure of Cx50 protein channel. Thus, it is supposed that the mutation causes cataracts in the Chinese family as a dominant-negative function mutation due to impaired function of the channel or reduced number of normal channels.[SUPPORTING:6]
Recently his group has applied single molecule techniques to study protein channel gating, develop new methods for studying biological membranes, and develop new approaches for biosensing.
Among the topics are carbon nanotubes as an idealized platform for protein channel mimetic pumps, responsive membranes for water treatment, magnetic nanocomposites for remote controlled responsive therapy and in vivo tracking, responsive colloids with controlled topology, and novel biomimetic polymer gels exhibiting self-oscillation.
