Cell Biol. 225:0-0(2026). CC -!- FUNCTION: Structural component of intermediate filaments in basal CC keratinocytes of stratified epithelia. Forms heteropolymers with type CC II keratin KRT5, contributing to the keratin intermediate filament CC network that confers mechanical strength and structural integrity to CC the basal layer of the epidermis and other stratified epithelial CC (PubMed:11724817, PubMed:1694855, PubMed:1720261, PubMed:41511042). The CC nonhelical tail domain is involved in promoting KRT5-KRT14 filaments to CC self-organize into large bundles and enhances the mechanical properties CC involved in resilience of keratin intermediate filaments in vitro CC (PubMed:11724817). Displays an antagonist role with KRT15 in basal CC epithelial cells, where KRT14 promotes cell differentiation while KRT15 CC maintains the progenitor state and promotes proliferation and CC clonogenicity (PubMed:41511042). Promotes cell differentiation by CC retaining YAP1 in the cytoplasm of basal keratinocytes via regulatory CC residue C367 and stratifin/SNF interaction (PubMed:41511042). CC Contributes to airway basal cell differentiation after injury CC (PubMed:36512409). {ECO:0000269|PubMed:11724817, CC ECO:0000269|PubMed:1694855, ECO:0000269|PubMed:1720261, CC ECO:0000269|PubMed:36512409, ECO:0000269|PubMed:41511042}.

Two heterodimers associate in an CC antiparallel manner to form heterotetramers, which further assemble CC into higher-order intermediate filaments (PubMed:1694855). Forms a CC disulfide-linked heterodimer (via 2B domains) with KRT5 (via 2B CC domains) (PubMed:1694855, PubMed:22705788, PubMed:24940650). Forms a CC heterodimer with KRT1; the interaction is more abundant in the absence CC of KRT5 (By similarity). Interacts with PLEC isoform 1C, when in a CC heterodimer with KRT5 (PubMed:24940650). Interacts with TRADD and with CC keratin filaments (PubMed:11684708). Interacts with EPPK1 (By CC similarity). Interacts with KLHL24 (PubMed:27798626). Interacts with CC PKP1 (via N-terminus) and PKP2 (PubMed:10852826).
