Background

Function：P13645: 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
P13646: Type 1 keratin (Probable). Maintains postnatal tongue mucosal cell homeostasis and tissue organization in response to mechanical stress, potentially via regulation of the G1/S phase cyclins CCNE1 and CCNE2 (By similarity)
P02533: The nonhelical tail domain is involved in promoting KRT5-KRT14 filaments to self-organize into large bundles and enhances the mechanical properties involved in resilience of keratin intermediate filaments in vitro
P08779: Epidermis-specific type I keratin that plays a key role in skin. Acts as a regulator of innate immunity in response to skin barrier breach: required for some inflammatory checkpoint for the skin barrier maintenance
P08727: Involved in the organization of myofibers. Together with KRT8, helps to link the contractile apparatus to dystrophin at the costameres of striated muscle

Subcellular Localization：P13645: Secreted, extracellular space; Cell surface; Cytoplasm
P02533: Cytoplasm; Nucleus

Expression：
Tissue_specificity: P13645: 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)
P13646: Expressed in some epidermal sweat gland ducts (at protein level) and in exocervix, esophagus and placenta
P02533: Expressed in the corneal epithelium (at protein level) (PubMed:26758872). Detected in the basal layer, lowered within the more apically located layers specifically in the stratum spinosum, stratum granulosum but is not detected in stratum corneum. Strongly expressed in the outer root sheath of anagen follicles but not in the germinative matrix, inner root sheath or hair (PubMed:9457912).
P19012: Expressed in a discontinuous manner in the basal cell layer of adult skin epidermis, but continuously in the basal layer of fetal skin epidermis and nail. Also expressed in the outer root sheath above the hair bulb in hair follicle (at protein level).
P08779: Expressed in the corneal epithelium (at protein level)
P08727: Expressed in a defined zone of basal keratinocytes in the deep outer root sheath of hair follicles. Also observed in sweat gland and mammary gland ductal and secretory cells, bile ducts, gastrointestinal tract, bladder urothelium, oral epithelia, esophagus, ectocervical epithelium (at protein level).
Induction: P13645: Repressed in keratinocytes by all-trans retinoic acid (ATRA) , via reduction of mRNA stability

Isoforms & Post-Translational Modification：P13646 has 3 isomers: P13646-1: 49588 Da (predicted); P13646-2: 38581 Da (predicted); P13646-3: 45867 Da (predicted).
O-glycosylated; glycans consist of single N-acetylglucosamine residues

Subunit：P13645: 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)
P13646: Heterotetramer of two type I and two type II keratins
P02533: Forms a disulfide-linked heterodimer (via 2B domains) with KRT5 (via 2B domains) (PubMed:22705788, PubMed:24940650).
P19012: Heterotetramer of two type I and two type II keratins (By similarity). Forms a heterodimer with KRT14 (PubMed:24940650). Interacts with PLEC isoform 1C, when in a heterodimer with KRT14 (PubMed:24940650). Interacts with NOD2 (PubMed:27812135)
P08779: Heterodimer of a type I and a type II keratin. KRT16 associates with KRT6 isomers (KRT6A or KRT6B) (By similarity). Interacts with TCHP (PubMed:15731013). Interacts with TRADD (By similarity)
P08727: Heterotetramer of two type I and two type II keratins. Interacts with PNN and the actin-binding domain of DMD. Interacts with HCV core protein
