Protein attributes

Sequence length	583 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Guanine nucleotide exchange factor for the small GTPase RALA. May be involved in cytoskeletal organization. May also be involved in the stimulation of transcription in a Ras-independent fashion By similarity.
Subunit structure	Interacts with the SH3 domains of GRB2 and PLCG1 By similarity. Interacts with RALA By similarity.
Subcellular location	Cytoplasm By similarity. Cell membrane By similarity. Note: Associates with membranes through the PH domain By similarity.
Domain	The PH domain mediates binding to phosphatidylinositol 4,5-biphosphate By similarity.
Involvement in disease	Note=RALGPS2 is a potential candidate gene for susceptibility to Alzheimer disease linked to 1q24. Ref.6
Sequence similarities	Contains 1 PH domain. Contains 1 Ras-GEF domain.
Sequence caution	The sequence CAH71098.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI21919.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI21925.1 differs from that shown. Reason: Erroneous gene model prediction.
