Protein: CCAAT-binding factor complex subunit php4 (O14318)
Organism: Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Function: Component of the transcription regulatory CCAAT-binding complex. Required for the reprogramming of the cell for iron use. Down-regulates pcl1, sdh4, and isa1 underlow-iron conditions.
Subcellular location: Cytoplasm {ECO:0000269|PubMed:19502236}. Nucleus {ECO:0000269|PubMed:16823372, ECO:0000269|PubMed:19502236}. Cytoplasm, cytoskeleton, spindle pole. Note=Iron starvation induces nuclear accumulation and iron induces relocalization to the cytoplasm, in association with exportin crm1. {ECO:0000269|PubMed:19502236}.
