Abstract:

Vertebrate photoreceptor outer segment (OS) morphogenesis requires peripherin/rds (P/rds). We have characterized this protein's C-terminus and present evidence that suggests it is intrinsically disordered. We propose that structural flexibility may underlie the multifunctionality proposed for this domain previously. The extremely short Ctermini present in other tetraspanin family members suggest that intrinsic disorder may also play a role for those proteins.

More about this publication?

Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
