Host cell factor C1 regulator 1 (HCFC1R1)

Regulates HCFC1 activity by regulating its subcellular localization. Overexpression of HCFC1R1 leads to accumulation of HCFC1 from the cytoplasm.

HCFC1R1-mediated export may offer the pool of cytoplasmic HCFC1 necessary for import of virion-derived VP16 into the nucleus. .
