From NCBI Gene:

The filaggrin-like protein encoded by this gene is upregulated by calcium, proteolyzed by calpain 1, and is involved in epithelial homeostasis. The encoded protein is required for proper cornification in skin, with defects in this gene being associated with skin diseases. This protein also has a function in skin barrier protection. In fact, in addition to providing a physical barrier, C-terminal fragments of this protein display antimicrobial activity against P. aeruginosa. [provided by RefSeq, Dec 2015]

From UniProt:

Essential for normal cell-cell adhesion in the cornified cell layers (PubMed:29758285). Important for proper integrity and mechanical strength of the stratum corneum of the epidermis (PubMed:29505760).

  • PEELING SKIN SYNDROME 6

From UniProt:

Peeling skin syndrome 6 (PSS6): A form of peeling skin syndrome, a genodermatosis characterized by generalized, continuous shedding of the outer layers of the epidermis. Two main PSS subtypes have been suggested. Patients with non-inflammatory PSS (type A) manifest white scaling, with painless and easy removal of the skin, irritation when in contact with water, dust and sand, and no history of erythema, pruritis or atopy. Inflammatory PSS (type B) is associated with generalized erythema, pruritus and atopy. It is an ichthyosiform erythroderma characterized by lifelong patchy peeling of the entire skin with onset at birth or shortly after. Several patients have been reported with high IgE levels. PSS6 patients manifest generalized ichthyotic dry skin, and bullous peeling lesions on the trunk and limbs at sites of minor trauma. Skin symptoms are exacerbated by warmth and humidity. PSS6 inheritance is autosomal recessive. [MIM:618084]
