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 leptin receptor is turned on (activated) by a hormone called leptin that attaches (binds) to the receptor, fitting into it like a key into a lock. Normally, the body's fat cells release leptin in proportion to their size. As fat cells become larger, they produce more leptin. This rise in leptin indicates that fat stores are increasing. In the hypothalamus, the binding of leptin to its receptor triggers a series of chemical signals that affect hunger and help produce a feeling of fullness (satiety).
