Protein attributes

Sequence length	747 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	Catalyzes the oxidation of sulfhydryl groups in peptide and protein thiols to disulfides with the reduction of oxygen to hydrogen peroxide. May contribute to disulfide bond formation in a variety of secreted proteins. In fibroblasts, it may have tumor-suppressing capabilities being involved in growth regulation. Ref.2 Ref.7 Ref.8 Ref.10 Ref.12 Ref.13
Catalytic activity	2 R'C(R)SH + O2 = R'C(R)S-S(R)CR' + H2O2. Ref.13
Cofactor	Binds 1 FAD per subunit. Ref.13 Ref.15
Subunit structure	Monomer. Ref.13 Ref.15
Subcellular location	Isoform 1: Golgi apparatus membrane; Single-pass membrane protein Ref.8 Ref.12. Isoform 2: Secreted › extracellular space. Note: Found in the extracellular medium of quiescent cells but is not found in proliferating cells. Ref.8 Ref.12
Tissue specificity	Expressed in heart, placenta, lung, liver, skeletal muscle, pancreas and very weakly in brain and kidney. Ref.8 Ref.9
Induction	Induced in quiescent cells just as fibroblasts begin to leave the proliferative cycle and enter quiescence. Ref.1 Ref.7 Ref.8
Miscellaneous	'Quiescin Q6' means that it was the sixth clone to be found at a higher level of expression in quiescent fibroblasts.
Sequence similarities	Belongs to the quiescin-sulfhydryl oxidase (QSOX) family. Contains 1 ERV/ALR sulfhydryl oxidase domain. Contains 1 thioredoxin domain.
Sequence caution	The sequence BAD92517.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
