Rho-related BTB domain-containing protein 1 is a protein that in humans is encoded by the RHOBTB1 gene. [5] [6]
The protein encoded by this gene belongs to the Rho family of the Ras superfamily of small GTPases. It contains a GTPase domain, a proline-rich region, a tandem of 2 BTB (broad complex, tramtrack, and bric-a-brac) domains, and a conserved C-terminal region. The protein plays a role in small GTPase-mediated signal transduction and the organization of the actin filament system. Alternate transcriptional splice variants have been characterized. [6]

Scinderin is a protein that in humans is encoded by the SCIN gene. Scinderin is an actin severing protein belonging to the gelsolin superfamily. It was discovered in Dr. Trifaro's laboratory at the University of Ottawa, Canada. Secretory tissues are rich in scinderin. In these tissues scinderin, a calcium dependent protein, regulates cortical actin networks. Normally secretory vesicles are excluded from release sites on the plasma membrane by the presence of a cortical actin filament network. During cell stimulation, calcium channels open allowing calcium ions to enter the secretory cell. Increase in intracellular calcium activates scinderin with the consequent actin filament severing and local dissociation of actin filament networks. This allows the movement of secretory vesicles to release sites on the plasma membrane.
