STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

ABCA12ATP-binding cassette sub-family A member 12; Probable transporter involved in lipid homeostasis; Belongs to the ABC transporter superfamily. ABCA family. (2595 aa)    
Predicted Functional Partners:
CYP4F22
Cytochrome P450 4F22; A cytochrome P450 monooxygenase involved in epidermal ceramide biosynthesis. Hydroxylates the terminal carbon (omega- hydroxylation) of ultra-long-chain fatty acyls (C28-C36) prior to ceramide synthesis. Contributes to the synthesis of three classes of omega-hydroxy-ultra-long chain fatty acylceramides having sphingosine, 6-hydroxysphingosine and phytosphingosine bases, all major lipid components that underlie the permeability barrier of the stratum corneum. Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second [...]

TGM1
Protein-glutamine gamma-glutamyltransferase K; Catalyzes the cross-linking of proteins and the conjugation of polyamines to proteins. Responsible for cross-linking epidermal proteins during formation of the stratum corneum. Involved in cell proliferation ; Belongs to the transglutaminase superfamily. Transglutaminase family.
   
  
 0.952
NIPAL4
Magnesium transporter NIPA4; Acts as a Mg(2+) transporter. Can also transport other divalent cations such as Ba(2+), Mn(2+), Sr(2+) and Co(2+) but to a much less extent than Mg(2+) (By similarity). May be a receptor for ligands (trioxilins A3 and B3) from the hepoxilin pathway.
   
  
 0.924
LIPN
Lipase member N; Plays a highly specific role in the last step of keratinocyte differentiation. May have an essential function in lipid metabolism of the most differentiated epidermal layers.
   
 
 0.830
CST6
Cystatin-M; Shows moderate inhibition of cathepsin B but is not active against cathepsin C; Belongs to the cystatin family.
   
  
 0.813
ALOXE3
Hydroperoxide isomerase ALOXE3; Non-heme iron-containing lipoxygenase which is atypical in that it displays a prominent hydroperoxide isomerase activity and a reduced dioxygenase activity compared to other lipoxygenases. The hydroperoxide isomerase activity catalyzes the isomerization of hydroperoxides, derived from arachidonic and linoleic acid by ALOX12B, into hepoxilin-type epoxyalcohols. The dioxygenase activity requires a step of activation of the enzyme by molecular oxygen. In presence of oxygen, oxygenates polyunsaturated fatty acids, including arachidonic acid, to produce fatty [...]

ALOX12B
Arachidonate 12-lipoxygenase, 12R-type; Catalyzes the regio and stereo-specific incorporation of a single molecule of dioxygen into free and esterified polyunsaturated fatty acids generating lipid hydroperoxides that can be further reduced to the corresponding hydroxy species. In the skin, acts upstream of ALOXE3 on the lineolate moiety of esterified omega-hydroxyacyl-sphingosine (EOS) ceramides to produce an epoxy-ketone derivative, a crucial step in the conjugation of omega-hydroxyceramide to membrane proteins. Therefore plays a crucial role in the synthesis of corneocytes lipid enve [...]

PNPLA1
Patatin-like phospholipase domain-containing protein 1; Lipid hydrolase. Important in the formation of the epidermal lipid barrier. Plays a role in glycerophospholipid metabolism.
   
  
 0.788
CERS3
Ceramide synthase 3; Ceramide synthase that catalyzes formation of ceramide from sphinganine and acyl-CoA substrates, with high selectivity toward very- long (C22:0-C24:0) and ultra long chain (more than C26:0) as acyl donor. It is crucial for the synthesis of ultra long-chain ceramides in the epidermis, to maintain epidermal lipid homeostasis and terminal. differentiation.
