Plays a role in the establishment of the epidermal barrier on plantar skin (By similarity). Involved in the maintenance of cell layer development and keratin filament bundles in suprabasal cells of the epithelium (By similarity). (Microbial infection) Acts as a mediator of S.aureus adherence to desquamated nasal epithelial cells via clfB, and hence may play a role in nasal colonization. (Microbial infection) Binds S.pneumoniae PsrP, mediating adherence of the bacteria to lung cell lines. Reduction of levels of KRT10 keratin decrease adherence, overexpression increases adherence. Neither protein has to be glycosylated for the interaction to occur. Heterotetramer of two type I and two type II keratins. Heterodimer with KRT1 (PubMed:24940650, PubMed:27595935). Two heterodimers of KRT1 and KRT10 form a heterotetramer (PubMed:27595935). The KRT10 subunit in the heterotetramer is probably disulfide-linked (PubMed:27595935). Interacts with PLEC isoform 1C, when in a heterodimer with KRT1 (PubMed:24940650). (Microbial infection) Interacts (via C-terminal tail domain) with the S.aureus clumping factor, clfB; this interaction probably mediates S.aureus attachment to the keratinized squamous epithelial cells from the nasal cavity. (Microbial infection) Interacts (via the C-terminal tail domain) with S.pneumoniae serine-rich repeat protein PsrP; this interaction probably mediates S.pneumoniae adherence to lung tissue and subsequent pathogenesis. Neither protein has to be glycosylated for the interaction to occur. Seen in all suprabasal cell layers including stratum corneum. Expressed on the surface of lung cell lines (PubMed:19627498). Localized on the surface of desquamated nasal epithelial cells (at protein level) (PubMed:12427098). Repressed in keratinocytes by all-trans retinoic acid (ATRA), via reduction of mRNA stability. A number of alleles are known that mainly differ in the Gly-rich region (positions 490-560). The disease is caused by variants affecting the gene represented in this entry. The disease is caused by variants affecting the gene represented in this entry. The disease is caused by variants affecting the gene represented in this entry. There are two types of cytoskeletal and microfibrillar keratin: I (acidic; 40-55 kDa) and II (neutral to basic; 56-70 kDa). Belongs to the intermediate filament family. Truncated N-terminus.
