RT   "A 62-kD sucrose binding protein is expressed and localized in tissues
RT   actively engaged in sucrose transport.";
RL   Plant Cell 4:1561-1574(1992).
CC   -!- FUNCTION: Plays a role in sucrose transport.
CC   -!- SUBCELLULAR LOCATION: Membrane; Peripheral membrane protein.
CC   -!- TISSUE SPECIFICITY: Associated with the plasma membrane of several cell
CC       types engaged in sucrose transport, including the mesophyll cells of
CC       young sink leaves, the companion cells of mature phloem and the cells
CC       of developing cotyledons.
CC   -!- DEVELOPMENTAL STAGE: In the cotyledon, expression is not detected until
CC       10 days after fertilization. Between 10-19 days after fertilization,
CC       expression increases rapidly but declines 20-30 days after
CC       fertilization. 30 days after fertilization, no expression occurs. This
CC       expression pattern closely parallels the rate of sucrose uptake in the
CC       cotyledon.
