View/Edit Human

Neutral ceramidase B also known as non-lysosomal ceramidase B or N-acylsphingosine amidohydrolase (non-lysosomal ceramidase) 2B or ASAH2B is a ceramidase enzyme which in humans is encoded by the ASAH2B gene.^[3][4]

Clinical significance

ASAH2B shows reduced expression with increasing age and further reduction in late onset Alzheimer's disease patients.^[3]
