GTPase, Calcium & Second Messenger Antibodies

GTPase, Calcium & Second Messenger Antibodies focus on signaling systems that convert extracellular or intracellular cues into fast and spatially organized responses. Small GTPases, heterotrimeric G proteins, calcium-binding proteins, cyclic nucleotide pathways, and lipid messengers regulate cytoskeletal dynamics, vesicle traffic, contraction, migration, secretion, and gene expression.

These antibodies support detection of signaling proteins that control switch-like activation, messenger production, ion-dependent signaling, and downstream pathway coordination. They are relevant for studies of cell movement, neuronal signaling, immune activation, receptor biology, cardiac and muscle function, and cancer-associated signaling changes.
