Function

May link Golgi membranes to the cytoskeleton and participate in the tensile force required for vesicle budding from the Golgi. Thereby, may play a role in Golgi membrane trafficking and could indirectly give its flattened shape to the Golgi apparatus. Alternatively, in concert with LURAP1 and CDC42BPA/CDC42BPB, has been involved in modulating lamellar actomyosin retrograde flow that is crucial to cell protrusion and migration. May be involved in the maintenance of the stromal cell architectures required for cell to cell contact. {ECO:0000269PubMed:19837035}.

Subcellular Localization

Isoform 1: Endoplasmic reticulum-Golgi intermediate compartment. Cytoplasm, cytoskeleton. Note=Colocalizes with actin.Isoform 2: Cytoplasm. Note=Lacks the PDZ domain. Diffusely localized in the cytoplasm.Golgi apparatus {ECO:0000250}. Golgi apparatus, trans-Golgi network {ECO:0000250}. Note=Recruited to the Golgi apparatus by GOLPH3. {ECO:0000250}.

Disease Associations

Tissue Specificity

Isoform 1 is expressed ubiquitously. Isoform 2 is specifically expressed in most hematopoietic cells.
