Palmitoyl-protein thioesterase 1; PPT-1; Palmitoyl-protein hydrolase 1; PPT1; PPT

For Research Use Only. Not for use in diagnostic procedures.

Polyclonal

Rabbit Ig

Rabbit

This PPT1 antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 189-217 amino acids from the Central region of human PPT1.

Peptide Affinity Purified Rabbit Polyclonal Antibody (Pab)

Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein A column, followed by peptide affinity purification.

Vial Concentration: 0.45 (lot specific)

Maintain refrigerated at 2-8 degree C for up to 6 months. For long term storage store at -20 degree C in small aliquots to prevent freeze-thaw cycles.

Small volumes of anti-PPT1 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

The protein encoded by this gene is a small glycoprotein
involved in the catabolism of lipid-modified proteins during
lysosomal degradation. The encoded enzyme removes thioester-linked
fatty acyl groups such as palmitate from cysteine residues. Defects
in this gene are a cause of infantile neuronal ceroid
lipofuscinosis 1 (CLN1, or INCL) and neuronal ceroid lipofuscinosis
4 (CLN4). Two transcript variants encoding different isoforms have
been found for this gene.

PPT1: Removes thioester-linked fatty acyl groups such as palmitate from modified cysteine residues in proteins or peptides during lysosomal degradation. Prefers acyl chain lengths of 14 to 18 carbons. Defects in PPT1 are the cause of neuronal ceroid lipofuscinosis type 1 (CLN1). A form of neuronal ceroid lipofuscinosis with variable age at onset. Infantile, late- infantile, juvenile, and ***** onset have been reported. Neuronal ceroid lipofuscinoses are progressive neurodegenerative, lysosomal storage diseases characterized by intracellular accumulation of autofluorescent liposomal material, and clinically by seizures, dementia, visual loss, and/or cerebral atrophy. The lipopigment pattern seen most often in CLN1 is referred to as granular osmiophilic deposits (GROD). Belongs to the palmitoyl-protein thioesterase family. 2 isoforms of the human protein are produced by alternative splicing.
