MIPs and Their Roles in the Exchange of Metalloids formatIsbn:Softcover 9781493941001 and autophosphorylation of the receptor 9783642096402 and autophosphorylation of the receptor then recruits other key regulatory proteins that initiate kinase cascades in which each phosphorylation event requires selective recognition of the protein substrate Since one of the major themes of RNA processing is the recognition of specific RNA sequences and structures by protein factors The respective MIP isoforms that facilitate the transport of these metalloids include members from several clades of the phylogenetic tree Sixteen years have passed since human aquaporin 1 (AQP1) was discovered as the first water channel
