Biological function summary
Connexin 32 plays a significant role in maintaining cellular communication networks. This protein forms hexameric complexes called connexons which dock with connexons of adjacent cells to create functional gap junction channels. These channels are essential in processes such as maintaining homeostasis cell differentiation and synchronized contraction of tissues like cardiac muscle. The structural formation allows direct transfer of metabolites and signaling molecules highlighting its importance in multicellular organism function.
Pathways
Connexin 32 actively contributes to cellular communication and metabolic coordination. It participates in the phosphoinositide 3-kinase (PI3-K) pathway and the ERK/MAPK signaling pathway which are important for cell growth proliferation and apoptosis. Connexin 32 interacts with proteins like Connexin 43 with both proteins playing roles in channel assembly and intracellular signaling processes that influence cellular responses to external stimuli.
