This family represents the tubulin epsilon and delta complex protein 1 (TEDC1). This complex is required for centriole maintenance and it is a component of several ciliary structures. It acts as a positive regulator of hedgehog signalling, which play key roles in embryonic development and in cancers [1]. Additionally, this protein may play a role in counteracting perturbation of actin filaments, such as after treatment with the actin depolymerising microbial metabolite Chivosazole F [2].
