Molecular cloning of the sphingolipid activator protein — 1 (SAP - 1), the sulfatide sulfatase activator

Biochemical and Biophysical Research Communications, 1986
A cDNA coding for SAP-1 was isolated from a lambda gt11 human hepatoma expression library using polyclonal antibodies raised against human SAP-1. Three positive clones were isolated with inserts of approximately 0.3 Kb (S1.1), 2 Kb (S1.2) and 2.2 Kb (S-1.3). The latter 2 contained an internal EcoRI site.

12 Activator Proteins for Sphingolipid Hydrolysis

1983
Publisher Summary This chapter focuses on the various activator proteins used for the sphingolipid hydrolysis. Mraz et al. found that human hepatic activator protein that was specific for stimulating the hydrolysis of galactosylceramide sulfate by human enzyme could also stimulate the same reaction catalyzed by acidic sulfatases isolated from various

[Disorders of sphingolipid activator proteins].

Nihon rinsho. Japanese journal of clinical medicine, 1996
Small-molecular nonenzymatic glycoproteins are necessary for degradation of sphingolipids in lysosomes. GM2 activator encoded by a gene on chromosome 5 is essential for hydrolysis of ganglioside GM2 and its asialo derivative. Mutations of this gene cause Tay-Sachs disease-like clinical phenotype (GM2-gangliosidosis AB variant).

The gene coding for a sphingolipid activator protein, SAP-1, is on human chromosome 10

Human Genetics, 1985
SAP-1 is a sphingolipid activator protein found in human tissues required for the enzymatic hydrolysis of GM1 ganglioside and sulfatide. It appears to be missing in patients who have a genetic lipidosis resembling juvenile metachromatic leukodystrophy.

Distribution of Saposins (Sphingolipid Activator Proteins) in Tissues of Lysosomal Storage Disease Patients

Journal of Molecular Neuroscience, 1992
Saposins are a group of small glycoproteins derived from a single precursor protein, prosaposin. Each of the four saposins are involved in lysosomal hydrolysis of various sphingolipids. Our recent investigations have shown that saposins accumulate in tissues of several lysosomal storage diseases patients, including those with Tay-Sachs disease and ...

Expression of Sphingolipid Activator Protein Gene in Brain and Systemic Organs of Developing Mice

Developmental Neuroscience, 1994
The sphingolipid activator proteins (SAPs) are a family of small, heat-stable glycoproteins, proven or postulated to be required for in vivo degradation of some sphingolipids by hydrolytic enzymes. Four of them are coded by a single gene, which generates a transcript including the four saps in tandem.

Structure of the lysosomal sphingolipid activator protein 1 by homology with influenza virus neuraminidase

Biochemical and Biophysical Research Communications, 1988
The sphingolipid activator protein 1 (SAP-1) increases the rate of hydrolysis of sphingolipids in the lysosome by apparently bringing together the substrate and the corresponding hydrolytic enzyme. This implies specific recognition of both the substrate and enzyme by SAP-1.

[Lysosomal enzymes, sphingolipid activator proteins, and protective protein].

Nihon rinsho. Japanese journal of clinical medicine, 1996
The lysosome is an intracytoplasmic acidic vacuole containing more than 60 hydrolytic enzymes for digestion of macromolecules, such as nucleic acids, proteins, lipids and complex carbohydrates. Expression of lysosomal enzyme activities is regulated by various intracellular environmental factors.
