GRIP1-associated protein 1 is a protein that in humans is encoded by the GRIPAP1 gene.^[5][6]

Function

GRASP1 is a neuron-specific guanine nucleotide exchange factor for the Ras family of small G proteins (RasGEF) and is associated with the GRIP/AMPA receptor complex in brain (Ye et al., 2000).[supplied by OMIM]^[6]

Interactions

GRIPAP1 has been shown to interact with GRIP1.^[5]
