Protein-coding gene in the species Homo sapiens
Mitochondrial import inner membrane translocase subunit TIM16 also known as presequence translocated-associated motor subunit PAM16 , mitochondria-associated granulocyte macrophage CSF-signaling molecule , or presequence translocated-associated motor subunit PAM16 is a protein that in humans is encoded by the PAM16 gene .[ 5] [ 6] [ 7]
The PAM16 gene is located on the p arm of chromosome 16 at position 13.3 and it spans 11,150 base pairs.[ 5] The PAM16 gene produces a 15.1 kDa protein composed of 137 amino acids .[ 8] [ 9] The structure has been found to contain a 21-residue mitochondrial targeting leader sequence.[ 10]
The PAM16 gene encodes for a mitochondrial protein with multiple functions. It is responsible for the regulation of ATP -dependent protein translocation into the mitochondrial matrix , inhibition of DNAJC19 stimulation of HSPA9 /Mortalin ATPase activity, and granulocyte-macrophage colony-stimulating factor (GM-CSF) signaling. Furthermore, PAM16 plays a role in the import of nuclear-encoded mitochondrial proteins into the mitochondrial matrix and may be important in reactive oxygen species (ROS) homeostasis .[ 7] [ 6] [ 5]
Clinical Significance [ edit ]
Mutations in the PAM16 gene has been shown to cause mitochondrial deficiencies and associated disorders. It is mainly associated with Megarbane-Dagher-Melike type spondylometaphyseal dysplasia , which is an autosomal recessive disease characterized by pre- and postnatal short stature , developmental delay , dysmorphic facial appearance, narrow chest , prominent abdomen , platyspondyly , short limbs , and other abnormalities of the skeleton .[ 6]
[ 7] [ 5]
PAM16 has been known to interact with PAM18 , DNAJC19 , TIMM17A , FEZ1 , TRIM25 , MARC1 , and other proteins.[ 11] [ 6] [ 7]
