Anti-NTE antibody (ab81387)

Phospholipase B that deacylates intracellular phosphatidylcholine (PtdCho), generating glycerophosphocholine (GroPtdCho). This deacylation occurs at both sn-2 and sn-1 positions of PtdCho. Its specific chemical modification by certain organophosphorus (OP) compounds leads to distal axonopathy.

Expressed in brain, placenta, kidney, neuron and skeletal muscle.

Defects in PNPLA6 are the cause of spastic paraplegia autosomal recessive type 39 (SPG39) [MIM:612020]; also known as NTE-related motor neuron disorder (NTEMND). Spastic paraplegia is a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. In some forms of the disorder, bladder symptoms (such as incontinence) may appear, or the weakness and stiffness may spread to other parts of the body. SPG39 is associated with a motor axonopathy affecting upper and lower limbs and resulting in progressive wasting of distal upper and lower extremity muscles.

Belongs to the NTE family.
Contains 3 cyclic nucleotide-binding domains.
Contains 1 patatin domain.

Glycosylated.

Endoplasmic reticulum membrane. Anchored to the cytoplasmic face of the endoplasmic reticulum by its amino-terminal transmembrane segment.
