For example, katanin-like 1 (KL1) is expressed in testicular Sertoli cells (SCs) from 15.5 days post-coitum, and KL1 loss of function contributes to male-specific infertility by disrupting SC microtubule dynamics and initiating premature release of spermatids from the seminiferous epithelium[8]. Here, KITLG is linked to Infertility.
