diphthamide biosynthesis protein 1 (DPH1 homolog, HsDph1, diphthamide biosynthesis protein 2 homolog-like 1, DPH2-like 1, diphthamide biosynthesis protein 2-like, DPH-like 1, ovarian cancer-associated gene 1 protein, DPH1, DPH2L, DPH2L1, OVCA1)
Function:
- required for the first step in the synthesis of diphthamide
- when overexpressed, suppresses colony formation ability & growth rate of ovarian cancer cells
- tumor suppressor in lung & breast cancers (putative)
- role in embryonic growth, organogenesis & postnatal survival (putative)
- interacts with DPH2 (putative)
- interacts with RBM8A
Structure: belongs to the DPH1/DPH2 family, DPH1 subfamily
Compartment:
- nucleus, cytoplasm
- punctate, primarily perinuclear localization
Alternative splicing: named isoforms=3
Expression:
- expressed in heart, brain, placenta, lung, liver, skeletal muscle, kidney, pancreas, spleen, thymus, mammary gland, colon, small intestine, testis & ovary
Pathology:
- diminished expression in primary breast & ovarian tumors
Note: uncertain whether Met-1 or Met-6 is the initiator
