"LALBA" - Alpha-lactalbumin in Homo sapiens
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

LALBAAlpha-lactalbumin; Regulatory subunit of lactose synthase, changes the substrate specificity of galactosyltransferase in the mammary gland making glucose a good acceptor substrate for this enzyme. This enables LS to synthesize lactose, the major carbohydrate component of milk. In other tissues, galactosyltransferase transfers galactose onto the N-acetylglucosamine of the oligosaccharide chains in glycoproteins; Belongs to the glycosyl hydrolase 22 family (142 aa)    
Predicted Functional Partners:
B4GALT1
Beta-1,4-galactosyltransferase 1; The Golgi complex form catalyzes the production of lactose in the lactating mammary gland and could also be responsible for the synthesis of complex-type N-linked oligosaccharides in many glycoproteins as well as the carbohydrate moieties of glycolipids; Beta 4-glycosyltransferases (398 aa)
       
  0.994
LCT
Lactase-phlorizin hydrolase; LPH splits lactose in the small intestine (1927 aa)
         
  0.930
GLB1
Beta-galactosidase; Cleaves beta-linked terminal galactosyl residues from gangliosides, glycoproteins, and glycosaminoglycans; Belongs to the glycosyl hydrolase 35 family (677 aa)
         
  0.916
GALE
UDP-glucose 4-epimerase; Catalyzes two distinct but analogous reactions- the reversible epimerization of UDP-glucose to UDP-galactose and the reversible epimerization of UDP-N-acetylglucosamine to UDP-N- acetylgalactosamine. The reaction with UDP-Gal plays a critical role in the Leloir pathway of galactose catabolism in which galactose is converted to the glycolytic intermediate glucose 6- phosphate. It contributes to the catabolism of dietary galactose and enables the endogenous biosynthesis of both UDP-Gal and UDP- GalNAc when exogenous sources are limited. Both UDP-sugar interconver [...] (348 aa)

CSN2
Beta-casein; Important role in determination of the surface properties of the casein micelles; Belongs to the beta-casein family (226 aa)
     
   
  0.907
GALT
Galactose-1-phosphate uridylyltransferase; Plays an important role in galactose metabolism (379 aa)
         
    0.900
HSPA8
Heat shock cognate 71 kDa protein; Molecular chaperone implicated in a wide variety of cellular processes, including protection of the proteome from stress, folding and transport of newly synthesized polypeptides, activation of proteolysis of misfolded proteins and the formation and dissociation of protein complexes. Plays a pivotal role in the protein quality control system, ensuring the correct folding of proteins, the re-folding of misfolded proteins and controlling the targeting of proteins for subsequent degradation. This is achieved through cycles of ATP binding, ATP hydrolysis a [...] (646 aa)

B4GALT2
Beta-1,4-galactosyltransferase 2; Responsible for the synthesis of complex-type N-linked oligosaccharides in many glycoproteins as well as the carbohydrate moieties of glycolipids. Can produce lactose; Beta 4-glycosyltransferases (401 aa)

CSN3
Kappa-casein; Kappa-casein stabilizes micelle formation, preventing casein precipitation in milk; Belongs to the kappa-casein family (182 aa)

CSN1S1
Alpha-S1-casein; Important role in the capacity of milk to transport calcium phosphate; Belongs to the alpha-casein family (185 aa)
