ENP — Lactuca sativa

Summary

LsENP, located on chromosome 4 of garden lettuce (Lactuca sativa), encodes an NPH3/RPT2-like protein containing BTB/POZ and NPH3 domains. The product is associated with FMN binding, blue light photoreceptor activity, GTPase activity, protein kinase activity, and telomeric repeat binding. It is linked to apical protein localization, regulation of auxin polar transport, chloroplast accumulation movement, cotyledon vascular tissue pattern formation, and basipetal auxin transport. Associations with traits include shoot axis phototropism, leaf yellowing tolerance, blue and red light sensitivity, biomass yield, seed yield, lateral root number and length, days to flowering, and submergence tolerance. The protein localizes to the apical plasma membrane, CRL complex, and ubiquitin ligase complex. Studies of related genes in other species link the family to phototropism, chloroplast migration, and stomatal aperture opening.
