-!- FUNCTION: May regulate the activity of kinases such as PKC and SRC
via binding to integrin beta-1 (ITB1) and the receptor of
activated protein C kinase 1 (RACK1). In complex with C1QBP is a
high affinity receptor for kininogen-1/HMWK.
{ECO:0000269|PubMed:17956333, ECO:0000269|PubMed:21544310}.
-!- SUBUNIT: Heterotetramer of two type I and two type II keratins.
Heterodimer with KRT10 (PubMed:27595935). Two heterodimers of KRT1
and KRT10 form a heterotetramer (PubMed:27595935). Interacts with
ITGB1 in the presence of RACK1 and SRC, and with RACK1
(PubMed:17956333). Interacts with C1QBP; the association
represents a cell surface kininogen receptor (PubMed:21544310).
Interacts with EPPK1; interaction is dependent of higher-order
structure of intermediate filament (PubMed:16923132).

-!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:17956333}.
Note=Located on plasma membrane of neuroblastoma NMB7 cells.
-!- TISSUE SPECIFICITY: The source of this protein is neonatal
foreskin. The 67-kDa type II keratins are expressed in terminally
differentiating epidermis.
-!- PTM: Undergoes deimination of some arginine residues
(citrullination). {ECO:0000269|PubMed:11841545,
ECO:0000269|PubMed:8780679}.
-!- POLYMORPHISM: There are two size variants of KRT1, termed allele
1A and allele 1B with allelic frequencies of 0.61 and 0.39. Allele
1B lacks 7 residues compared to allele 1A.
-!- DISEASE: Epidermolytic hyperkeratosis (EHK) [MIM:113800]: An
autosomal dominant skin disorder characterized by widespread
blistering and an ichthyotic erythroderma at birth that persist
into adulthood. Histologically there is a diffuse epidermolytic
degeneration in the lower spinous layer of the epidermis. Within a
few weeks from birth, erythroderma and blister formation diminish
and hyperkeratoses develop. {ECO:0000269|PubMed:10232403,
ECO:0000269|PubMed:10688370, ECO:0000269|PubMed:10844506,

ECO:0000269|PubMed:9856846}. Note=The disease is caused by
mutations affecting the gene represented in this entry.
-!- DISEASE: Ichthyosis hystrix, Curth-Macklin type (IHCM)
[MIM:146590]: A genodermatosis with severe verrucous
hyperkeratosis. Affected individuals manifest congenital verrucous
black scale on the scalp, neck, and limbs with truncal erythema,
palmoplantar keratoderma and keratoses on the lips, ears, nipples
and buttocks. {ECO:0000269|PubMed:11286616}. Note=The disease is
caused by mutations affecting the gene represented in this entry.
-!- DISEASE: Keratoderma, palmoplantar, non-epidermolytic (NEPPK)
[MIM:600962]: A dermatological disorder characterized by well-
demarcated hyperkeratosis is present over the palms and soles. A
red band is frequently present at the periphery of the keratosis.
It is usually non-transgredient, with a sharp demarcation of the
lesions at the wrists. {ECO:0000269|PubMed:11286630,
ECO:0000269|PubMed:7528239}. Note=The disease is caused by
mutations affecting the gene represented in this entry.
-!- DISEASE: Ichthyosis annular epidermolytic (AEI) [MIM:607602]: A
skin disorder resembling bullous congenital ichthyosiform
erythroderma. Affected individuals present with bullous ichthyosis
in early childhood and hyperkeratotic lichenified plaques in the
flexural areas and extensor surfaces at later ages. The feature
that distinguishes AEI from BCIE is dramatic episodes of flares of
annular polycyclic plaques with scale, which coalesce to involve
most of the body surface and can persist for several weeks or even
months. {ECO:0000269|PubMed:10053007,
ECO:0000269|PubMed:10597140}. Note=The disease is caused by
mutations affecting the gene represented in this entry.
-!- DISEASE: Keratoderma, palmoplantar, striate 3 (SPPK3)
[MIM:607654]: A dermatological disorder characterized by
thickening of the stratum corneum and epidermal layers on palms
and soles. There is no involvement of non-palmoplantar skin, and
both hair and nails are normal. {ECO:0000269|PubMed:11982762}.
Note=The disease is caused by mutations affecting the gene
represented in this entry.
-!- MISCELLANEOUS: There are two types of cytoskeletal and
microfibrillar keratin: I (acidic; 40-55 kDa) and II (neutral to
basic; 56-70 kDa).
-!- SIMILARITY: Belongs to the intermediate filament family.
{ECO:0000255|PROSITE-ProRule:PRU01188}.
-!- CAUTION: A peptide corresponding to residues 278 to 289 was
isolated as part of plant proteomics studies and was originally
thought to be of plant origin (PubMed:18602030, PubMed:19412582,
PubMed:16529377). However, it was later shown that it is likely to
be human type II keratin, a common contaminant in proteomic
analyses (PubMed:23895828). {ECO:0000305|PubMed:23895828}.
