Gene

Locus

SMIM11 is located on the plus strand of chromosome 21 and has 4 exons.[4]

Expression of SMIM11A in human tissue samples

Expression

The expression of SMIM11 is highest in the brain, thyroid, and stomach, though it is also expressed in many other tissues.[4]

mRNA

There are no known transcript variants or isoforms of SMIM11.[5]

Protein

The SMIM11 protein is 58 amino acids long. The theoretical molecular weight of this protein is 6kDa and the theoretical pI is 9.[6] The protein is localized in the cytoplasm and mitochondria, as well as focal adhesion points between the cells.[7][8]

Domains, Motifs, and Post-translational Modifications

SMIM11 contains a transmembrane domain.[9] The protein also holds a dileucine motif. Post-translational modifications include ubiquitylation site, as well as two phosphorylated sites, one on a threonine and one on a serine[10][11]

Secondary Structure and Tertiary Structure

The protein is composed mostly of alpha-helices.[12] The N-terminus of SMIM11 sticks out into the extracellular matrix, while the C-terminal end is located within the cytoplasm of the cell.[13]

Tertiary Structure of SMIM11

Quaternary Structure and Protein Interactions

Experimentally-determined protein interactions for SMIM11 have not yet been identified.[14]
