Figure 1. Types of GIPLs.
For information on M2, M3, iM2, GIPL-A, isoM3 and isoM4, see introduction. Fatty acid chains vary in different GIPL species: The predominant type fatty acid in Type-1 and Hybrid GIPLs is C18∶0, in type-2 GIPLs the predominant lipids are C18∶0, C22∶0 C24∶0 and C26∶0. “R” in Type 1 GIPLs represent a protein linked to the GIPL structure by a ethanolamine phosphate residue (e.g. gp63 surface metalloprotease) [31], [78].
