General annotation (Comments)

Function

Converts proline to delta-1-pyrroline-5-carboxylate.

Catalytic activity

L-proline + acceptor = (S)-1-pyrroline-5-carboxylate + reduced acceptor. Ref.3

Cofactor

FAD. Ref.3

Pathway

Amino-acid degradation; L-proline degradation into L-glutamate; L-glutamate from L-proline: step 1/2.

Subcellular location

Mitochondrion matrix.

Tissue specificity

Expressed in lung, skeletal muscle and brain, to a lesser extent in heart and kidney, and weakly in liver, placenta and pancreas.

Induction

During TP53-induced apoptosis. Ref.7

Involvement in disease

Defects in PRODH are the cause of hyperprolinemia type 1 [MIM:239500]. It is a disorder characterized by elevated serum proline levels. May be involved in the psychiatric and behavioral phenotypes associated with the 22q11 velocardiofacial and DiGeorge syndrome. Ref.8

Defects in PRODH may be associated with susceptibility to schizophrenia 4 (SCZD4) [MIM:600850]. Schizophrenia [MIM:181500] is a psychosis, a disorder of thought and sense of self. Although it affects emotions, it is distinguished from mood disorders in which such disturbances are primary. Similarly, there may be mild impairment of cognitive function, and it is distinguished from the dementias in which disturbed cognitive function is considered primary. No objective biological test for schizophrenia exists. Schizophrenia is a common disorder with a lifetime prevalence of approximately 1%. It is highly heritable but the genetics are complex. A subset of schizophrenia patients present hyperprolinemia type 1. Ref.9

Sequence similarities

Belongs to the proline oxidase family.
