Abstract
- OCT4 plays critical roles in self-renewal and pluripotency maintenance of embryonic stem cells, and is considered as one of the main stemness markers. It also has pivotal roles in early stages of embryonic development. Most studies on OCT4 have focused on the expression and function of OCT4A, which is the biggest isoform of OCT4 known so far. Recently, many studies have shown that OCT4 has various transcript variants, protein isoforms, as well as pseudogenes. Distinguishing the expression and function of these variants and isoforms is a big challenge in expression profiling studies of OCT4. Understanding how OCT4 is functioning in different contexts, depends on knowing of where and when each of OCT4 transcripts, isoforms and pseudogenes are expressed. Here, we review OCT4 known transcripts, isoforms and pseudogenes, as well as its interactions with other proteins, and emphasize the importance of discriminating each of them in order to understand the exact function of OCT4 in stem cells, normal development and development of diseases.
