Insulin like 6 is a
protein that in humans is encoded by the INSL6
gene.
[5]
Function
The protein encoded by this gene contains a classical signature of the
insulin superfamily and is significantly similar to
relaxin and relaxin-like factor. This gene is preferentially expressed in
testis. Its expression in testis is restricted to
interstitial cells surrounding
seminiferous tubules, which suggests a role in
sperm development and
fertilization.
