Connexin43 regulates sodium current; ankyrin-G modulates gap junctions: the intercalated disc exchanger.
Intercalated disc structures have conventionally been considered to be independent. Recent work shows that molecules initially thought of as belonging to one complex can actually affect another. Here, I focus on the cross-talk between connexin43 (Cx43, 'the gap junction protein') and the sodium channel complex and, conversely, on ankyrin-G (AnkG, a 'component of the sodium channel complex') and...
متن کاملCell-, age- and stage-dependent distribution of connexin43 gap junctions in testes.
Immunocytochemical data demonstrate that the distribution of gap junction connexin43 (Cx43) in rodent testes is dependent on cell type, testis maturation, and stage of the mature seminiferous epithelium. Western blotting and indirect immunofluorescence microscopy using anti-peptide antisera to Cx43 revealed abundant Cx43 in rat and mouse testes and mouse TM3 and TM4 cells. Cx43 mRNA was detecte...
متن کاملConnexin43 and Bergmann Glial Gap Junctions in Cerebellar Function
Connexin43 (Cx43), a major component of astrocytic gap junctions, is abundantly expressed in Bergmann glial cells (BGCs) in the cerebellum, but the function of Cx43 in BGCs is largely unknown. BGCs are specialized astrocytes closely associated with Purkinje cells. Here, we review our recent studies of the role of Cx43 in gap junctional coupling between BGCs and in cerebellar function. We genera...
متن کاملEndocytic processing of connexin43 gap junctions: a morphological study.
Gap junctions are plasma membrane areas enriched in channels that provide direct intercellular communication. Gap junctions have a high turnover rate; however, the mechanisms by which gap junctions are degraded are incompletely understood. In the present study, we show that in response to phorbol ester treatment, the gap junction channel protein Cx43 (connexin43) is redistributed from the plasm...
متن کاملE-cadherin differentially regulates the assembly of Connexin43 and Connexin32 into gap junctions in human squamous carcinoma cells.
It is as yet unknown how the assembly of connexins (Cx) into gap junctions (GJ) is initiated upon cell-cell contact. We investigated whether the trafficking and assembly of Cx43 and Cx32 into GJs were contingent upon cell-cell adhesion mediated by E-cadherin. We also examined the role of the carboxyl termini of these Cxs in initiating the formation of GJs. Using cadherin and Cx-null cells, and ...
