2.A.29.4.3
Phosphate carrier, Pic1: (PTP1; Mir1) (Hamel et al., 2004).  Also transports short chain (methane) phosphonates and medium chain (C12, C14 and C16) fatty acids which competitively inhibit phosphate transport (Engstová et al. 2001).  The Hansenula polymorpha Mir1 is dually localized in peroxisomes and mitochondria (Pedersen et al. 2024).
