InterPro domain: IPR019443

The function of the FMP27 protein is not known. FMP27 is the product of a nuclear encoded gene but it is detected in highly purified mitochondria in high-throughput studies [ 1 ].

This domain is found in fungi, metazoans and plants. These include FMP27 and "maize" protein APT1 and Arabidopsis homologues SABRE and KIP.APT1 is required for pollen tube growth. It is a Golgi-localised protein and appears to regulate vesicular trafficking [ 2 ]. SABRE and KIP are APT1 homologues and they are involved in the elongation of root cortex cells and pollen tubes respectively.
