Rabbit Anti-UVRAG/FITC Conjugated antibody
background:
UVRAG, also known as p63 or DHTX, is a 699 amino acid cytoplasmic protein. UVRAG has been shown to activate the BECN1/PI 3-kinase complex, which promotes autophagy. Autophagy is the degradation of cellular proteins in the lysosomes, and when this pathway is suppressed, cell growth is deregulated. Mutations in the gene encoding UVRAG have been associated with colon cancer, suggesting that UVRAG is also involved in suppressing the proliferation and tumorigenicity of human colon cancer cells. UVRAG has been found to complement the ultraviolet sensitivity of xeroderma pigmentosum group C cells. Ubiquitously expressed, UVRAG is found at highest levels in kidney, lung, liver and brain. UVRAG contains one C2 domain, which is thought to be involved in calcium-dependent phospholipid binding.
Subunit:
Forms a complex with BECN1, PIK3C3 and PIK3R4. A subpopulation of these complexes also harbor KIAA0226/Rubicon. UVRAG-containing complexes never including ATG14, both forming mutually exclusive complexes with BECN1 through direct competition. Directly interacts with FEZ1 and SCOC. The interaction with SCOC is reduced by amino acid starvation, but the complex is stabilized in the presence of FEZ1.
Subcellular Location:
Late endosome. Lysosome. Early endosome. Colocalizes with RAB9-positive compartments involved in retrograde transport from late endosomes to trans-Golgi network. Colocalization with early endosomes is only partial.
Tissue Specificity:
Highly expressed in brain, lung, kidney and liver.
DISEASE:
Note=A chromosomal aberration involving UVRAG has been observed in a patient with heterotaxy (left-right axis malformation). Inversion Inv(11)(q13.5;q25).
Similarity:
Contains 1 C2 domain.
