ANN5 — Cicer arietinum

Summary

CaANN5 (LOC101488440) on chickpea chromosome 6 encodes an annexin family protein containing annexin repeats and a conserved annexin superfamily domain. The product binds calcium ions, phospholipids (including phosphatidylserine), and F-actin, and is a structural constituent of the cytoskeleton. It localises to the plasma membrane, cytosol, endoplasmic reticulum, mitochondria, plasmodesmata, plant-type cell wall, and exocytic vesicles. CaANN5 is associated with calcium-ion-regulated exocytosis, protein trimerization, secretion, cytoskeleton organisation, developmental growth, fruit ripening, and responses to red/far-red light, oxidative stress, heat, cold, salinity, and thirst. It has been linked to pollen tube growth, pollen germination, pollen membrane integrity, pollen development, embryo development, and flowering time. Studies of related genes in other species connect the annexin family to abiotic stress response, vegetative-to-reproductive transition, and embryo development traits.
