Background: LAMP-1/CD107a

LAMP-1 (lysosome-associated membrane protein 1), also known as CD107a (cluster of differentiation 107a), is a major component of lysosomal membranes that plays an important role in lysosomal biogenesis, autophagy, and cholesterol metabolism (1). LAMP-1 is a type I transmembrane glycoprotein that is expressed on plasma membranes and the membranes of endosomes, autolysosomes, and lysosomes (1,2). Additionally, LAMP-1/CD107a is a commonly used marker for natural killer (NK) cell degranulation (3). LAMP-1 and another lysosomal-associated membrane protein, LAMP-2, together make up about half of all lysosome membrane proteins (1). Additionally, LAMP-1 has a role in presenting carbohydrate ligands to selectins (2). Human LAMP-1 protein is comprised of 417 amino acids (aa) with a theoretical molecular weight of 44.8 kDa; however, glycosylation can increase the molecular weight upwards of 120 kDa (1, 4). Structurally, LAMP-1 protein contains a large luminal/extracellular domain (29-382 aa), a helical transmembrane domain (383-405 aa), and a short cytoplasmic tail (406-417 aa) (1,2). Additionally, the protein has many N- and O-linked glycosylation sites which helps with stability in the membrane (1,2).

LAMP-1 plays an important role in autophagy-mediated ATP-release during apoptosis where lysosomes containing intracellular ATP migrate to the plasma membrane and, during exocytosis, LAMP-1 is exposed to the cell surface (5). Studies have found that knockdown of LAMP-1 blocks the ATP release from the cell (5). Furthermore, an absence of LAMP-1 and LAMP-2 leads to an accumulation of lysosomal cholesterol (6). Lysosomal membrane dysfunction or defects has also been associated with disease development (6,7). For example, one feature of pancreatitis is autophagy impairment which is caused by lysosomal dysfunction and a corresponding decrease in lysosomal-membrane associated proteins LAMP-1 and LAMP-2 (7).

  • Q: I am currently interested in developing a CD107a degranulation assay with sheep cells. I have been looking at your anti-CD107a antibodies that react with bovine samples (ref NBP2-25155 and NBP2-25154), as anti-bovine antibodies can cross react with sheep samples. I have seen on your webpage that both antibodies have been tested in WB and in immunofluorescence. I was wondering whether you have tested them for flow cytometry as it is the application we are intending to use in the lab. I was also wondering whether you could send us a sample of either antibody so that we can test them in sheep and for this application.

    A:

    Neither of these have been tested in FLOW. We do have a great progam that will allow you to try these antibodies in any species or application that has not been tested and if you share your results with us you will earn a voucher for the cost of the product for a future puchase. This is called the innovators reward. If you would like to test an antibody in an untested species and/or application and share your results with us, I can recommend our Innovator's Reward™ program. Our Innovator’s Reward™ program was created to allow researchers the opportunity to try our primary antibodies in an untested species or application, without the financial risk of failure. To participate you simply submit an online review detailing your positive or negative results. In return, you receive a discount voucher for 100% of the purchase price of the reviewed product. As such we do not provide free samples. I apologize for this.
