Abstract:Most protists possess a unique membrane skeleton, the epiplasm, which is involved in pattern forming processes of the cell cortex and functions in maintaining cell shape. Articulins, a novel class of cytoskeletal proteins, are major constituents of the epiplasm. We have isolated cDNAs encoding the two major articulins of the ciliate Pseudomicrothorax dubius. Peptide sequence data confirm the identity of the cloned cDNAs encoding articulins 1 and 4. With the data presented here sequence information for all majo… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
