General annotation (Comments)

Function

Plays a neuroprotective role in the eye and optic nerve. Probably part of the TNF-alpha signaling pathway that can shift the equilibrium toward induction of cell death. May act by regulating membrane trafficking and cellular morphogenesis via a complex that contains Rab8 and hungtingtin (HD). May constitute a cellular target for adenovirus E3 14.7, an inhibitor of TNF-alpha functions, thereby affecting cell death. Ref.2

Subunit structure

Interacts with E3 14.7 kDa protein of group C human adenovirus. Interacts with HD. Interacts with Rab8 (RAB8A and/or RAB8B). Interacts with transcription factor IIIA (GTF3A). Ref.1 Ref.6 Ref.7 Ref.9

Subcellular location

Cytoplasmperinuclear region. Golgi apparatus. Note: Found in the perinuclear region and associates with the Golgi apparatus. Ref.2 Ref.1 Ref.8

Tissue specificity

Present in acqueous humor of the eye (at protein level). Highly expressed in trabecular meshwork. Expressed nonpigmented ciliary epithelium, retina, brain, adrenal cortex, fetus, lymphocyte, fibroblast, skeletal muscle, heart, liver, brain and placenta. Ref.2 Ref.1

Induction

Upon TNF-alpha and interferon treatments. Ref.1 Ref.8 Ref.10 Ref.11

Post-translational modification

Phosphorylated. Phosphorylation is induced by phorbol esters and decreases its half-time. Ref.8 Ref.12

Involvement in disease

Defects in OPTN are the cause of primary open angle glaucoma type 1E (GLC1E) [MIM:137760]. Primary open angle glaucoma (POAG) is characterized by a specific pattern of optic nerve and visual field defects. The angle of the anterior chamber of the eye is open, and usually the intraocular pressure is increased. The disease is asymptomatic until the late stages, by which time significant and irreversible optic nerve damage has already taken place. Ref.2 Ref.14 Ref.15 Ref.17 Ref.18 Ref.19

Defects in OPTN are a cause of susceptibility to normal pressure glaucoma (NPG) [MIM:606657]. Ref.20

Caution

According to some authors (Ref.10) its expression is regulated by intraocular pressure, suggesting a protective role in case of high pressure, while according to other authors (Ref.11), it is not up-regulated in response to pressure elevation.

Sequence caution

The sequence CAI16552.1 differs from that shown. Reason: Erroneous gene model prediction.

Alternative products

This entry describes 3 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q96CV9-1)

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.
Isoform 2 (identifier: Q96CV9-2)

The sequence of this isoform differs from the canonical sequence as follows:
     210-215: Missing.
Note: No experimental confirmation available.
Isoform 3 (identifier: Q96CV9-3)

The sequence of this isoform differs from the canonical sequence as follows:
     1-57: Missing.
