Protein contentin humans have a huge role to play in regards to managing the standard levels of lachrymal glands, and other such functions of the human body. Coded within the protein gene, this has its basic lineage in eukaryote, vertebrata, chordate, craniata, and other types of organisms. The Human Proline-rich protein 4 can be said to be a group of proteins that are structured on an intrinsic note. The type 4 is specifically encoded within PRR4 sample, and hence, it can be said to lack a specific and conserved domain, that might result in binding of this with others. However, since, it is left alone; one can surely note that it has a major role to play in regards to specific functions that are associated with the eyes. As per the tests that have been conducted, a fine analysis of this has resulted in checking out how this protein had a role to play in regards to regulation of proteome, during moments of relax tearing.

Functions and associated aspects of Human Proline-rich protein 4:

There is a number of splicing that is caused with help of multiple variants. Though a number of studies have been left pending, but the important factor is that it has a role to play in the ocular surface that requires much exploration. It has also been revealed that the presence of such increased protein content, there is an increase in reflex tears that are to be used in certain cases. This has been evidently found in usage of Human Proline-rich protein 4(PRR4) ELISA Kit that are being used now for tests.
