Syntaxin-5 is a protein that in humans is encoded by the STX5 gene. [5] [6] [7]
STX5 has been shown to interact with:
Golgin subfamily A member 2 is a protein that in humans is encoded by the GOLGA2 gene.
General vesicular transport factor p115 is a protein that in humans is encoded by the USO1 gene.
Syntaxin-6 is a protein that in humans is encoded by the STX6 gene.
Coatomer subunit alpha is a protein that in humans is encoded by the COPA gene.
N-ethylmaleimide-sensitive factor Attachment Protein Alpha, also known as SNAP-α, is a SNAP protein that is involved in the intra-cellular trafficking and fusing of vesicles to target membranes in cells.
Coatomer subunit epsilon is a protein that in humans is encoded by the COPE gene.
Golgi reassembly-stacking protein of 65 kDa (GRASP65) also known as Golgi reassembly-stacking protein 1 (GORASP1) is a protein that in humans is encoded by the GORASP1 gene.
Vesicle-associated membrane protein 3 is a protein that in humans is encoded by the VAMP3 gene.
Synaptobrevin homolog YKT6 is a protein that in humans is encoded by the YKT6 gene.
Syntaxin-8 is a protein that in humans is encoded by the STX8 gene. Syntaxin 8 directly interacts with HECTd3 and has similar subcellular localization. The protein has been shown to form the SNARE complex with syntaxin 7, vti1b and endobrevin. These function as the machinery for the homotypic fusion of late endosomes.
Golgi SNAP receptor complex member 1 is a protein that in humans is encoded by the GOSR1 gene.
BET1-like protein is a protein that in humans is encoded by the BET1L gene.
Vesicle-associated membrane protein 4 is a protein that in humans is encoded by the VAMP4 gene.
Conserved oligomeric Golgi complex subunit 3 is a protein that in humans is encoded by the COG3 gene.
Vesicle-trafficking protein SEC22b is a protein that in humans is encoded by the SEC22B gene.
BET1 homolog is a protein that in humans is encoded by the BET1 gene.
Syntaxin-16 is a protein that in humans is encoded by the STX16 gene.
Golgi SNAP receptor complex member 2 is a protein that in humans is encoded by the GOSR2 gene.
Syntaxin 17 is a protein that in humans is encoded by the STX17 gene. In horses a duplication in intron 6 causes progressive graying.
The Golgi matrix is a collection of proteins involved in the structure and function of the Golgi apparatus. The matrix was first isolated in 1994 as an amorphous collection of 12 proteins that remained associated together in the presence of detergent and 150 mM NaCl. Treatment with a protease enzyme removed the matrix, which confirmed the importance of proteins for the matrix structure. Modern freeze etch electron microscopy (EM) clearly shows a mesh connecting Golgi cisternae and associated vesicles. Further support for the existence of a matrix comes from EM images showing that ribosomes are excluded from regions between and near Golgi cisternae.
