Native Human Cathepsin D

• Cat.No.: CTSD-27858TH
• Product Overview: Full length native mature Cathepsin D protein purified from Human liver.

Specification

• Description: This gene encodes a lysosomal aspartyl protease composed of a dimer of disulfide-linked heavy and light chains, both produced from a single protein precursor. This proteinase, which is a member of the peptidase C1 family, has a specificity similar to but narrower than that of pepsin A. Transcription of this gene is initiated from several sites, including one which is a start site for an estrogen-regulated transcript. Mutations in this gene are involved in the pathogenesis of several diseases, including breast cancer and possibly Alzheimer disease.
• Biological activity: Specific activity:541 Units/mg (prior to lyophilization).One unit is the amount of enzyme which digests hemoglobin releasing peptides which are soluble in 10% TCA.The reaction is measured by an increase of an A280 of 1.0 per 60 minutes at 37oC.Substrate:
• Form: Lyophilised:Reconstitute with 28.3ul distilled water. Protein: 0.883mg/ml (prior to lyophilization).
• Purity: >95% by SDS-PAGE
• Storage buffer: Preservative: NoneConstituents: 2mM Sodium phosphate, pH 6.5
• Storage: Shipped at 4°C. Upon delivery aliquot and store at -20°C. Avoid freeze / thaw cycles.
• Sequence Similarities: Belongs to the peptidase A1 family.

Q&As

What is the relationship between CTSD proteins and cognitive function?

There is an association between CTSD proteins and cognitive function. In some neurodegenerative diseases, abnormal accumulation and deposition of CTSD proteins may affect neuronal signaling and synaptic function, leading to a decline in cognitive function.

What is the relationship between changes in CTSD protein levels and disease?

In some neurodegenerative diseases, levels of the CTSD protein may change. For example, people with Alzheimer's disease may have elevated levels of the CTSD protein. These changes may help in the diagnosis of the disease and in the assessment of the course of the disease.

For people with cognitive decline, how do you assess their CTSD protein levels?

For people with cognitive decline, their CTSD protein levels can be assessed by a blood or cerebrospinal fluid sample. This evaluation can help doctors understand whether the cause of cognitive decline is related to a neurodegenerative disease.

How can treatment be used to alter the level or function of the CTSD protein?

It is currently no treatment that directly targets the CTSD protein. However, some medications can reduce symptoms of neurodegenerative diseases, such as cholinesterase inhibitors such as donepezil, which can increase acetylcholine levels in synapses, which can improve cognitive function.

Is CTSD protein involved in Parkinson's disease?

People with Parkinson's disease may have reduced levels of the CTSD protein. This decrease may be associated with neuronal death and impaired synaptic function. In addition, CTSD protein may also be associated with motor symptoms in patients with Parkinson's disease.

In which diseases does the CTSD protein play a role?

CTSD proteins play a role in Alzheimer's disease, Parkinson's disease, and other neurodegenerative diseases. It may change in these diseases, leading to structural alterations and impaired signaling of neuronal synapses.
