Vasohibin 1 (VASH1)

Vasohibin protein contains a cluster of basic amino acids in its C terminus and no classic secretion signal sequence. Vasohibin expression was robust between embryonic weeks 6 to 12 in heart, brain, kidney, lung, skeletal muscle, and whole embryo. Immunohistochemical analysis detected vasohibin at the endothelial layer of placenta and brain.

The deduced protein contains 365 amino acids. RT-PCR ELISA detected intermediate expression in adult heart, brain, lung, liver, kidney, ovary, and spinal cord, as well as in fetal brain. Lower expression was detected in skeletal muscle, testis, pancreas, and fetal liver, and little to no expression was detected in spleen. All specific adult brain regions examined showed low to moderate expression.
