LIP1 — Pisum sativum

Summary

PSAT7G050920 (LIP1) in garden pea encodes a sphingosine N-acyltransferase subunit lip1, a protein with a P-loop NTPase domain and GTPase activity that also binds GTP and proteins. It is associated with strigolactone anabolism and response, photomorphogenesis, skotomorphogenesis, dark adaptation, circadian regulation of gene expression, and signal transduction. The gene is linked to intracellular and vesicle transport, protein transport, and stress response. It localises to the vacuolar membrane, plasmalemma, cytoplasm, and nucleus. Phenotypic associations include shortened circadian period and altered light response. Studies of related small GTPase family members in other species further connect this family to intracellular trafficking and signalling processes.
