Abstract:
Lymphotoxin (LT) deficient mice have profound defects in the splenic microarchitecture associated with defective expression on certain gene products, including chemokines. By using subtraction cloning of splenic cDNA from wild-type and LT alpha or TNF/LT alpha double deficient mice we isolated a novel murine gene encoding a secretory type phospholipase A2, called SPLASH. The two major alternative transcripts of SPLASH gene are predominantly expressed in lymphoid tissues, such as spleen and lymph nodes. SPLASH maps to the distal part of chromosome 4, to which several cancer-related loci have been also mapped.

Flippase
Eukaryotic flippases are type-IV P-type ATPases or P4-ATPases belonging to P-type ATPase family proteins that are membrane-bound pumps involved in the ATP-mediated transport of ions and molecules across the membrane. Flippases flip specific phospholipids from the outer to the inner leaflet of a membrane. All P4-ATPases have one...
