Human BTN1A1 / Butyrophilin Protein, His Tag

Source : 

Human BTN1A1, His Tag (BT1-H5222) is expressed from human 293 cells (HEK293). It contains AA Ala 27 - Arg 242 (Accession # AAH96312).

 

Molecule : BTN1A1

 

Synonyms : BTN1A1,Butyrophilin,BTN

 

Format : Powder

 

Category : Immune Checkpoint Proteins

 

Accession : AAH96312

Characteristics :

This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 25.8 kDa. The protein migrates as 35-40 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

 

Endotoxin Level : Less than 1.0 EU per μg by the LAL method.

 

Buffer : PBS, pH7.4

 

Description :

Butyrophilin subfamily 1 member A1 (BTN1A1) is also known as BTN, which is a member of the immunoglobulin superfamily and the major protein associated with fat droplets in the milk. BTN1A1 may have a cell surface receptor function. The human butyrophilin gene is localized in the major histocompatibility complex (MHC) class I region of 6p and may have arisen relatively recently in evolution by the shuffling of exons between 2 ancestral gene families. Furthermore, BTN1A1 regulates the amount of lipids and size of droplets expressed in milk and inhibits the proliferation of CD4 and CD8 T-cells activated by anti-CD3 antibodies, T-cell metabolism and IL2 and IFNG secretion.
