N-terminal C2 in EEIG1 and EHBP1 proteins This version of the C2 domain was initally identified in the vertebrate estrogen early-induced gene 1 (EEIG1), and its Drosophila ortholog required for uptake of dsRNA via the endocytotic machinery to induce RNAi silencing. It is also in C.elegans ortholog Sym-3 (SYnthetic lethal with Mec-3) and the mammalian protein EHBP1 (EH domain Binding Protein-1) that regulates endocytotic recycling and two plant proteins, RPG that regulates Rhizobium-directed polar growth and PMI1 (Plastid Movement Impaired 1) that is essential for intracellular movement of chloroplasts in response to blue light. |
