The Fos gene family consists of 4 members: FOS, FOSB, FOSL1, and FOSL2. These genes encode leucine zipper proteins that can dimerize with proteins of the JUN family, thereby forming the transcription factor complex AP-1. As such, the FOS proteins have been implicated as regulators of cell proliferation, differentiation, and transformation. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2014]
A study in rats demonstrated that the FOSL1 protein exhibits time-sensitive expression in contused skeletal muscle, with significant increases observed at 4, 8, and 32-48 hours post-injury, while showing no significant change in contralateral uninjured muscle or in post-mortem specimens for up to 24 hours [Sun et al. DOI:10.1080/00450618.2017.1334824]. In human skin, the FOSL1 was identified as a critical driver of keratinocyte migration during acute wound healing, with its expression transiently upregulated at wound edges and its silencing significantly reducing keratinocyte motility [Liu et al. DOI:10.1016/j.stem.2024.11.013]. In a separate study investigating UVB-induced inflammatory pain in humans and rats, the FOSL1 was found to be up-regulated in skin, with a fold change of 93.1 in human and 10.9 in rat skin, indicating its role in the cellular stress response to this inflammatory stimulus [Dawes et al. DOI:10.1371/journal.pone.0093338].
