Target Species

Human

Target Name

MIEF1

Target Full Name

Mitochondrial dynamics protein MIEF1

Target Function

Mitochondrial outer membrane protein which regulates mitochondrial fission. Promotes the recruitment and association of the fission mediator dynamin-related protein 1 (DNM1L) to the mitochondrial surface independently of the mitochondrial fission FIS1 and MFF proteins. Regulates DNM1L GTPase activity and DNM1L oligomerization. Binds ADP and can also bind GDP, although with lower affinity. Does not bind CDP, UDP, ATP, AMP or GTP. Inhibits DNM1L GTPase activity in the absence of bound ADP. Requires ADP to stimulate DNM1L GTPase activity and the assembly of DNM1L into long, oligomeric tubules with a spiral pattern, as opposed to the ring-like DNM1L oligomers observed in the absence of bound ADP. Does not require ADP for its function in recruiting DNM1L.

Target Subcellular Location

Mitochondrion outer membrane; Single-pass membrane protein.

Target Protein Families

SMCR7 family

Target Tissue Specificity

Expression is relatively high in heart, skeletal muscle, pancreas and kidney.

Target Synonyms

MIEF1; MID51; SMCR7L; Mitochondrial dynamics protein MID51; Mitochondrial dynamics protein of 51 kDa; Mitochondrial elongation factor 1; Smith-Magenis syndrome chromosomal region candidate gene 7 protein-like; SMCR7-like protein

Target Background

Enables ADP binding activity; GDP binding activity; and identical protein binding activity. Involved in several processes, including positive regulation of mitochondrial fission; positive regulation of mitochondrial translation; and positive regulation of protein targeting to membrane. Located in mitochondrial matrix and mitochondrial outer membrane. Colocalizes with mitochondrial large ribosomal subunit.
