Irp-1A | Iron regulatory protein 1A (Irp-1A) encodes a cytosolic aconitase that under iron deficiency (or if cytosolic superoxide is present) loses its iron-sulfur cluster, changes confirmation and binds iron regulatory elements (so far identified on the products of SdhB and Fer1HCH mRNAs); Belongs to the aconitase/IPM isomerase family. (902 aa) | ||||
porin | Voltage-dependent anion-selective channel; Porin (porin) encodes a beta-barrel channel protein localized in the outer membrane of mitochondria that conducts translocation of various ions and metabolites between cytoplasm and mitochondria. It plays roles in mitochondria dynamics and mitophagy, and is ubiquitinated by the E3 ligases encoded by park and Mul1. (282 aa) | ||||
Irp-1B | Iron regulatory protein 1B (Irp-1B) encodes a cytosolic aconitase highly homologous to the product of Irp-1A; Belongs to the aconitase/IPM isomerase family. (899 aa) |
