Maintains stem cell potency (By similarity). Increases STAT3 phosphorylation and controls ERK phosphorylation (By similarity). May act as a scaffold, increasing STAT3 recruitment onto endosomes (By similarity). Interacts with STAT3. The OCIA domain is necessary and sufficient for endosomal localization. 'Asrij' stands for 'blood' in Sanskrit as this protein is strongly expressed in blood vessels. Belongs to the OCIAD1 family.
