We investigated the fourth subgroup of Arabidopsis aquaporin, small and basic intrinsic proteins (SIPs). When they were expressed in yeast, SIP1;1 and SIP1;2, but not
SIP2
;1, gave water-channel activity. The transient expression of SIPs linked with green fluorescent protein in Arabidopsis cells and the subcellular fractionation of the tissue homogenate showed their ER localization. The SIP proteins were detected in all of the tissues, except for dry seeds. Histochemical analysis of promoter-
beta-glucuronidase
fusions revealed the cell-specific expression of SIPs. SIP1;1 and SIP1;2 may function as water channels in the ER, while
SIP2
;1 might act as an ER channel for other small molecules or ions.
