Here is a breakdown of the source code representation of a Java class. A class can be broken down into two things: 1  The first piece is a class-header which consists of the keyword  class  and the name you give to the class. 2  Names in programming languages are also known as identifiers. 3  The second piece is the body.
The long isoform consists of 1162 amino acids and is the only Leptin receptor isoform with clearly demonstrated signaling capability [1]. Leptin signaling occurs typically through the JAK/STAT pathway. Janus kinase 2 (JAK2) activation leads to tyrosine phosphorylation of Leptin receptor. Phosphorylated Tyr1138 of Leptin receptor serves as a binding site for STAT proteins.
The MAPK/ERK pathway is a chain of proteins in the cell that communicates a signal from a receptor on the surface of the cell to the DNA in the nucleus of the cell. The signal starts when a signaling molecule binds to the receptor on the cell surface and ends when the DNA in the nucleus expresses a protein and produces some change in the cell, such as cell division. The pathway includes many proteins, including MAPK, which communicate by adding phosphate groups to a neighboring protein, which ac
