Can you provide a list of molecules which insulin bind

Insulin primarily binds to the insulin receptor (INSR) on the surface of target cells. However, there are certain molecules that can also interact with insulin. Here are a few examples:

1. Insulin-like growth factor 1 (IGF-1): IGF-1 is structurally similar to insulin and can bind to the insulin receptor, although it has a higher affinity for the IGF-1 receptor.

2. Insulin-like growth factor 2 (IGF-2): Similar to IGF-1, IGF-2 can also bind to the insulin receptor but has a higher affinity for the IGF-2 receptor.

3. Insulin-like peptides (ILPs): ILPs are a group of peptide hormones found in insects, and they share structural similarities with human insulin. They can bind to the insulin receptor in insects.

4. Insulin analogs: Various synthetic insulin analogs have been developed for therapeutic use in diabetes management. These analogs are designed to mimic the action of endogenous insulin and bind to the insulin receptor.

It's important to note that the primary interaction of insulin occurs with the insulin receptor, while other molecules may have varying affinities and effects on insulin signaling.
