General annotation (Comments)

Function	May play a cooperative role in NF2-mediated growth suppression of cells By similarity. Ref.4 UniProtKB Q96HU1
Subunit structure	Interacts with GJA1. Interaction with GJA1 induces its degradation. Interacts via its RUN domain with the C-terminal region of NF2. Interacts with RAB3A, RAB4A, RAB5A, RAB8A, RAB11A, RAP1A, RAP1B, RAP2A, RAP2B and PDCD6I. No interaction with RAB27A By similarity. UniProtKB Q96HU1 Ref.1
Subcellular location	Cytoplasm By similarity. UniProtKB Q96HU1
Tissue specificity	Widely expressed. Ref.4
Sequence similarities	Belongs to the small G protein signaling modulator family. Contains 1 Rab-GAP TBC domain. Contains 1 RUN domain. Contains 1 SH3 domain.
