Xic is a cis-acting locus that contains the information necessary to count X chromosomes and inactivate all copies but one. Inactivation spreads from Xic along the entire X chromosome.

In the nucleus, gibberellin binds to the GID1 receptor and induces a conformational change in the N-terminal domain of the receptor, allowing the receptor to interact with the TVHYNP and DELLA domains of the DELLA repressor.

The formation of the GID1-repressor complex promotes the interaction between the repressor and the E3 ubiquitin ligase SCF-SLY, leading to the ubiquitination and degradation of the DELLA repressor by the 26S proteasome.

ANDROGEN-INSENSITIVITY SYNDROME

These individuals have female external sexual characteristics. Vagina ends blindly and that the uterus, oviducts, and ovaries are absent.

 Inside the abdominal cavity, a pair of testes produce levels of testosterone normally seen in males. 

Woman with androgen-insensitivity syndrome contain an X and a Y chromosome. 

Testosterone bind to an androgen receptor. This receptor is defective in females with androgen-insensitivity syndrome.

The gene for the androgen receptor is located on the X chromosome
