BTNL9 (Butyrophilin-like protein 9) is a single pass type I transmembrane protein belonging to the BTN/MOG family of the immunoglobulin (Ig) superfamily (IgSF). Butyrophilin (BTN) is the major protein associated with fat droplets in the milk.  The BTN genes are a group of major histocompatibility complex (MHC)-associated genes that encode type I transmembrane proteins with 2 extracellular immunoglobulin (Ig) domains and an intracellular B30.2/SPRY (PRYSPRY) domain. Three subfamilies of human BTN genes are located in the MHC class I region: the single-copy BTN1A1 gene and the BTN2 (e.g., BTN2A1) and BTN3 (e.g., BNT3A1) genes, which have undergone tandem duplication, resulting in 3 copies of each.  BTNL9 contains 1 Ig-like V-type (IgV) domain in the extracelluar region (ECD).   BTNL9’s function remains unclear.

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
