Protein attributes

Sequence length	235 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Has an important function as a repair enzyme for proteins that have been inactivated by oxidation. Catalyzes the reversible oxidation-reduction of methionine sulfoxide in proteins to methionine.
Catalytic activity	Peptide-L-methionine + thioredoxin disulfide + H2O = peptide-L-methionine (S)-S-oxide + thioredoxin. L-methionine + thioredoxin disulfide + H2O = L-methionine (S)-S-oxide + thioredoxin.
Subcellular location	Isoform 1: Mitochondrion Ref.2 Ref.3 Ref.10. Isoform 2: Cytoplasm Ref.2 Ref.3 Ref.10. Isoform 3: Cytoplasm. Nucleus Ref.2 Ref.3 Ref.10. Isoform 5: Cytoplasm. Membrane; Lipid-anchor Ref.2 Ref.3 Ref.10.
Tissue specificity	Ubiquitous. Highest expression in adult kidney and cerebellum, followed by liver, heart ventricles, bone marrow and hippocampus.
Sequence similarities	Belongs to the MsrA Met sulfoxide reductase family.

Alternative products

This entry describes 5 isoforms produced by alternative promoter usage, alternative splicing and alternative initiation. [Align] [Select]

Note: Only about 25% of mRNAs are initiated at the mitochondrial isoform 1 codon.

Isoform 1 (identifier: Q9UJ68-1)

Also known as: MsrA1; mitoMSRA; a;

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.

Note: Mitochondrial. Produced by alternative splicing.

Isoform 2 (identifier: Q9UJ68-2)

Also known as: MsrA2; d;

The sequence of this isoform differs from the canonical sequence as follows:
     1-66: Missing.

Note: Cytoplasmic. Produced by alternative promoter usage.

Isoform 3 (identifier: Q9UJ68-3)

Also known as: MsrA3; cytoMSRA; c;

The sequence of this isoform differs from the canonical sequence as follows:
     1-48: MLSATRRACQLLLLHSLFPVPRMGNSASNIVSPQEALPGRKEQTPVAA → MCSEP

Note: Cytoplasmic and nuclear. Produced by alternative promoter usage.

Isoform 4 (identifier: Q9UJ68-4)

Also known as: b;

The sequence of this isoform differs from the canonical sequence as follows:
     71-110: Missing.

Note: Produced by alternative splicing.

Isoform 5 (identifier: Q9UJ68-5)

The sequence of this isoform differs from the canonical sequence as follows:
     1-22: Missing.

Note: Cytoplasmic. Myristoylated at Gly-2. Produced by alternative initiation.
