The BSCL2 gene provides instructions for making a protein called seipin. Seipin is located in the membrane of a cell structure called the endoplasmic reticulum. The endoplasmic reticulum modifies newly produced proteins and helps transport proteins, fats, and other molecules to where they are needed.
Normal function
The BSCL2 gene provides instructions for making a protein called seipin. Seipin is located in the membrane of a cell structure called the endoplasmic reticulum. The endoplasmic reticulum modifies newly produced proteins and helps transport proteins, fats, and other molecules to where they are needed.
Three different versions (isoforms) of the seipin protein can be produced from the BSCL2 gene. One isoform is found in most tissues, and the other two are specific to the brain and the nervous system outside of the brain.
Studies suggest that seipin plays a critical role in the development and function of adipocytes, which are the major component of fatty (adipose) tissue. Within the endoplasmic reticulum of adipocytes, seipin is involved in the formation of lipid droplets, which are structures that store fat molecules.

¿Puedo tomar Fenofibrato y Gabapentina juntos?
Hay no known significant interactions between fenofibrate and gabapentin. These two medicines work in different ways and are processed by different organs in the body. Why this happens Fenofibrate is primarily broken down by the liver and affects blood fats (lipids). Gabapentin is not metabolised by the liver; it is filtered out of the body.
