Antibody Specificity: High
Antibody Cross Reactivity: No significant cross-reactive proteins detected in HepG2 and A431 cells, but a 75 kDa medium cross-reactive protein can be observed in both celll lnes, and a ~50 kDa medium cross-reactive protein in A431cells.

Scientific Background: ESYT1 binds glycerophospholipids in a barrel-like domain and may play a role in cellular lipid transport. It binds calcium (via the C2 domains) and translocates to sites of contact between the endoplasmic reticulum and the cell membrane in response to increased cytosolic calcium levels. It helps to tether the endoplasmic reticulum to the cell membrane and promotes the formation of appositions between the endoplasmic reticulum and the cell membrane.
