Summary: Predicted to enable GTPase activator activity. Predicted to be involved in positive regulation of axon extension; positive regulation of neuron migration; and small GTPase-mediated signal transduction. Predicted to act upstream of or within Rho protein signal transduction. Located in actin cytoskeleton; cell cortex; and postsynaptic density. Is expressed in several structures, including brain; genitourinary system; liver; lung; and spleen. Used to study autism spectrum disorder. Orthologous to human ARHGAP32 (Rho GTPase activating protein 32). [provided by Alliance of Genome Resources, Dec 2024]

Our results suggest that PX-RICS-mediated GABAAR trafficking is a key target for GABAergic plasticity and its dysfunction leads to atypical emotional processing underlying autism.
Title: The Autism-Related Protein PX-RICS Mediates GABAergic Synaptic Plasticity in Hippocampal Neurons and Emotional Learning in Mice.
PX-RICS-deficient mice exhibit ASD-like social behaviours and ASD-related comorbidities. PX-RICS-deficient neurons show reduced surface gamma-aminobutyric acid type A receptor (GABAAR) levels and impaired GABAAR-mediated synaptic transmission.
Title: PX-RICS-deficient mice mimic autism spectrum disorder in Jacobsen syndrome through impaired GABAA receptor trafficking.
leptin stimulates the MAPK pathways and CREB dependent transcription. This then leads to an increase in miR132 that suppresses expression of the Rac1 inhibitor p250GAP, thus activating Rac1 and promoting synaptogenesis.
Title: Leptin induces hippocampal synaptogenesis via CREB-regulated microRNA-132 suppression of p250GAP.
Overexpression of p250GAP abolishes brain-derived neurotrophic factor (BDNF)-induced branching.
Title: BDNF promotes axon branching of retinal ganglion cells via miRNA-132 and p250GAP.
Cdh1-APC together with the RhoA regulators p250GAP and Smurf1 controls axon growth in the mammalian brain
Title: p250GAP is a novel player in the Cdh1-APC/Smurf1 pathway of axon growth regulation.
Results suggest that PX-RICS ensures the efficient entry of the N-cadherin/beta-catenin complex into the secretory pathway, and thereby regulates the amount of N-cadherin available for cell adhesion and FGFR4-mediated signaling.
Title: PX-RICS mediates ER-to-Golgi transport of the N-cadherin/beta-catenin complex.
These results suggest that PX-RICS is involved in early brain development including extension of axons and dendrites, and postnatal remodeling and fine-tuning of neural circuits.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
