Store lyophilized/reconstituted at -20°C; make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
For reconstitution add 50 µL of sterile water.
Specific Species Reactivity: Arabidopsis thaliana, Oryza sativa
TIP1 encodes a membrane-associated S-acyl transferase that localizes to endomembrane compartments and functions broadly in plant cell expansion, with especially prominent roles in polarized tip growth of root hairs and pollen tubes; loss-of-function alleles (tip1-1 and tip1-2) cause short, frequently branched root hairs, impaired pollen tube growth, and overall growth defects, consistent with a requirement for TIP1 activity in both tip growth and diffuse (non-tip) cell growth. Structurally, TIP1 is an ankyrin repeat-containing DHHC cysteine-rich domain protein (a DHHC palmitoyltransferase family member), with multiple N-terminal ankyrin repeats that are thought to mediate protein-protein interactions and a conserved DHHC catalytic motif within a cysteine-rich region that binds palmitate and supports enzymatic S-acylation; in functional assays, TIP1 can substitute for a yeast S-acyl transferase mutant and chemical inhibition of protein acylation phenocopies the tip1 root-hair defect, linking its molecular activity to growth control. Biologically, TIP1-dependent S-acylation is expected to regulate the membrane association, trafficking, and/or spatial activity of proteins required for cell surface expansion and polarized secretion, providing a mechanistic basis for its impact on root hair morphogenesis and general plant growth, and is distinct from tonoplast aquaporin TIP1;1 and TIP1;2, whose complete loss produces only mild physiological effects under standard conditions.
