== Disease ==
[https://www.uniprot.org/uniprot/FILA_HUMAN FILA_HUMAN] Autosomal dominant ichthyosis vulgaris. The disease is caused by mutations affecting the gene represented in this entry.  Disease susceptibility is associated with variations affecting the gene represented in this entry.
== Function ==
[https://www.uniprot.org/uniprot/FILA_HUMAN FILA_HUMAN] Aggregates keratin intermediate filaments and promotes disulfide-bond formation among the intermediate filaments during terminal differentiation of mammalian epidermis.

== Publication Abstract from PubMed ==
The fused-type S100 protein profilaggrin and its proteolytic products including filaggrin are important in the formation of a normal epidermal barrier; however, the specific function of the S100 calcium-binding domain in profilaggrin biology is poorly understood. To explore its molecular function, we determined a 2.2 A-resolution crystal structure of the N-terminal fused-type S100 domain of human profilaggrin with bound calcium ions. The profilaggrin S100 domain formed a stable dimer, which contained two hydrophobic pockets that provide a molecular interface for protein interactions. Biochemical and molecular approaches demonstrated that three proteins, annexin II/p36, stratifin/14-3-3 sigma, and Hsp27, bind to the N-terminal domain of human profilaggrin; one protein (stratifin) co-localized with profilaggrin in the differentiating granular cell layer of human skin. Together, these findings suggest a model where the profilaggrin N-terminus uses calcium-dependent and calcium-independent protein-protein interactions to regulate its involvement in keratinocyte terminal differentiation and incorporation into the cornified cell envelope.Journal of Investigative Dermatology accepted article preview online, 11 March 2015. doi:10.1038/jid.2015.102.
