WebJan 3, 2024 · Some aquaporins only transport water. Others have evolved to co-facilitate the transport of glucose (see above), glycerol, urea, ammonia, carbon dioxide and even ions (protons) along with water. Like other carrier proteins, aquaporins are allosterically regulated to allow cells to meet their specific water balance requirements. WebJan 16, 2024 · They have several basic amino acids at the C-terminal. Among the 35 full-length aquaporin genes of the Arabidopsis genome, 13 encode for PIPs [ 22 ]. Based on the sequence similarities, PIPs are classified into two subgroups, PIP1s and PIP2s.
