Guanine nucleotide exchange factor (GEF) for RHOA and RAC1 GTPases (PubMed:8643598, PubMed:22155786, PubMed:27418539).

Involved in coordinating actin remodeling, which is necessary for cell migration and growth (PubMed:10341202, PubMed:22155786).

Plays a key role in the regulation of neurite outgrowth and lamellipodia formation (PubMed:32109419).

In developing hippocampal neurons, limits dendrite formation, without affecting the establishment of axon polarity. Once dendrites are formed, involved in the control of synaptic function by regulating the endocytosis of AMPA-selective glutamate receptors (AMPARs) at CA1 excitatory synapses (By similarity).

May act as a regulator of adipogenesis (By similarity).

The disease is caused by variants affecting the gene represented in this entry.
Disease descriptionAn autosomal dominant form of mental retardation, a disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. MRD63 is characterized by moderate to severe impaired intellectual development with poor or absent speech, global developmental delay, and variable behavioral abnormalities. Variable dysmorphic features are preset in half of the patients.

<p>The checksum is a form of redundancy check that is calculated from the sequence.
