General annotation (Comments)

Function

Promotes guanine-nucleotide exchange on ARF1. Promotes the activation of ARF through replacement of GDP with GTP By similarity.

Subunit structure

Binds via its PH domain to the inositol head group of phosphotidylinositol 3,4,5-trisphosphate with high affinity. Interacts with GRASP By similarity.

Subcellular location

Cell membrane By similarity.

Tissue specificity

Present in all tissues tested, with highest protein levels in brain and adrenal.

Developmental stage

On embryonic days 15 (E15) and E18, expressed in the cortical plate of the cerebrum. On postnatal days 0 (P0) and P7, a moderate expression is seen in the cerebral neocortex, hippocampal pyramidal and dentate granule cell layers. In the cerebellum, expressed in the cerebellar Purkinje cells. On P14, a decreased expression is seen throughout the brain. On P21, expression is seen in the cerebellar Purkinje cells, dentate granule cells and the hippocampal pyramidal cells. Ref.2

Sequence similarities

Contains 1 PH domain.

Contains 1 SEC7 domain.
