Summary: Predicted to enable guanyl-nucleotide exchange factor activity and small GTPase binding activity. Involved in autophagy of mitochondrion and intracellular signal transduction. Located in mitochondrion and plasma membrane. Human ortholog(s) of this gene implicated in attention deficit hyperactivity disorder and immunodeficiency 40. Orthologous to several human genes including DOCK2 (dedicator of cytokinesis 2); DOCK4 (dedicator of cytokinesis 4); and DOCK5 (dedicator of cytokinesis 5).

What's a GeneRIF?

Rho5 rapidly relocates from the plasma membrane to mitochondria upon glucose starvation, mediated by its dimeric GDP/GTP exchange factor (GEF) Dck1/Lmo1.
Title: The Small Yeast GTPase Rho5 and Its Dimeric GEF Dck1/Lmo1 Respond to Glucose Starvation.
A regulatory role in autophagy/mitophagy is suggested by the colocalization of Rho5 with autophagic markers and the decreased mitochondrial turnover observed in dck1, lmo1 and rho5 deletion mutants. Rho5 activation may thus serve as a central hub for the integration of different signaling pathways.
Title: Identification of Dck1 and Lmo1 as upstream regulators of the small GTPase Rho5 in Saccharomyces cerevisiae.

Preferred Names: Dck1p

NP_013526.1

Dock family protein (Dedicator Of CytoKinesis), homolog of human DOCK1; upstream component for regulation through the small GTPase Rho5p; may form a complex with Lmo1p that acts as a GEF for Rho5p; interacts with Ino4p; cytoplasmic protein that relocates to mitochondria under oxidative stress; implicated in mitophagy; not an essential protein; DOCK proteins act as guanine nucleotide exchange factors
