Overview of Gene Research
Niban2, with currently no widely-known common aliases, has been found to be tightly associated with multiple biological processes. It is involved in pathways related to bone formation, cell migration, and may play a role in immune-related functions. In bone, it promotes osteoblast differentiation, which is crucial for maintaining normal bone structure and preventing osteoporosis [1].
Conditional Niban2 knockout in osteoblasts led to bone loss and insufficient mineralization, demonstrating its key role in bone formation. Mechanistically, Niban2 interacts with the HNRNPU-cored spliceosome complex, regulating the alternative splicing of RUNX2. This results in an increase in functional RUNX2 (nuclear localization sequence complete) and a decrease in dysfunctional RUNX2 (exon 6 exclusive), ultimately reinforcing osteoblast differentiation.
Additionally, in bovine cloned placentation, NIBAN2 was upregulated, and in human endometrial sEV-mediated trophoblast invasion, NIBAN2 was among the upregulated proteins related to embryo implantation. Also, in FLT3-mutated AML, NIBAN2 was identified as a candidate biomarker associated with FLT3 inhibitor sensitivity [1,2,3,4].
In conclusion, Niban2 plays essential roles in bone formation, potentially through its regulation of RUNX2 alternative splicing. Its involvement in processes like cell migration during placentation and as a biomarker in AML indicates its broad-reaching biological significance. The conditional knockout mouse model in osteoblasts has been particularly valuable in revealing its role in bone-related diseases such as osteoporosis.
