Crocc2, a member of the rootletin family, is integral to cellular functions and is expressed prominently in various tissues, including the central nervous system, dorsal root ganglion, embryo mesenchyme, and lung. As a ciliary rootlet coiled-coil protein, Crocc2 likely plays a crucial role in the organization and maintenance of ciliary structures, contributing to cellular processes in diverse tissues. The activation of Crocc2 involves a complex interplay of signaling pathways influenced by various chemicals. These chemicals act directly or indirectly on Crocc2 expression, modulating its levels in different tissues. For instance, retinoic acid directly up-regulates Crocc2 by binding to retinoic acid receptors, enhancing its transcription and subsequent expression in the embryo mesenchyme. Indirect activators, such as forskolin and PMA, modulate cAMP/PKA and PKC signaling, respectively, influencing Crocc2 expression in tissues like the dorsal root ganglion.

Understanding the activation mechanisms of Crocc2 sheds light on its functional significance, particularly in ciliary structure and cellular organization. The intricate interplay of chemicals influencing various signaling pathways underscores the complex regulatory network governing Crocc2 expression. Further exploration of the specific roles of Crocc2 in diverse tissues promises to deepen our understanding of its contributions to cellular structure and function.
