The following guanine nucleotide exchange factors (GEFs) were shown to bind RHOQ and catalyze GDP to GTP exchange on RHOQ, resulting in formation of the active RHOQ:GTP complex:
ITSN1 (Jaiswal et al. 2013)
OBSCN (Coisy-Quivy et al. 2009)
PREX1 (Jaiswal et al. 2013)

ARHGEF9 was implicated as a RHOQ GEF by some (Papadopoulos et al. 2015) but not all (Jaiswal et al. 2013; Mayer et al. 2013) studies and is annotated as a candidate RHOQ GEF.

The following GEFs do not act on RHOQ:
AKAP13 (also known as Lbc) (Zheng et al. 1995)
ARHGEF1 (Jaiswal et al. 2011; Jaiswal et al. 2013)
ARHGEF11 (Jaiswal et al. 2011; Jaiswal et al. 2013)
ARHGEF12 (Jaiswal et al. 2011; Jaiswal et al. 2013)
ARHGEF2 (also known as GEF-H1) (Ren et al. 1998)
ARHGEF28 (Jaiswal et al. 2011; Jaiswal et al. 2013)
ARHGEF4 (also known as Asef) (Gotthardt and Ahmadian 2007; Jaiswal et al. 2013)
ARHGEF5 (Wang et al. 2009)
DNMBP (Jaiswal et al. 2013)
MCF2 (Jaiswal et al. 2013)
MCF2L (Jaiswal et al. 2013)
TIAM1 (Jaiswal et al. 2013)
TRIO (Jaiswal et al. 2013)
VAV2 (Jaiswal et al. 2013)
