STRINGSTRING
NAPSA protein (human) - STRING interaction network
"NAPSA" - Napsin-A 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

NAPSANapsin-A; May be involved in processing of pneumocyte surfactant precursors (420 aa)    
Predicted Functional Partners:
SFTPB
Pulmonary surfactant-associated protein B; Pulmonary surfactant-associated proteins promote alveolar stability by lowering the surface tension at the air- liquid interface in the peripheral air spaces. SP-B increases the collapse pressure of palmitic acid to nearly 70 millinewtons per meter (393 aa)
     
 
  0.957
SFTPC
Pulmonary surfactant-associated protein C; Pulmonary surfactant associated proteins promote alveolar stability by lowering the surface tension at the air- liquid interface in the peripheral air spaces; BRICHOS domain containing (197 aa)
     
 
  0.932
NKX2-1
Homeobox protein Nkx-2.1; Transcription factor that binds and activates the promoter of thyroid specific genes such as thyroglobulin, thyroperoxidase, and thyrotropin receptor. Crucial in the maintenance of the thyroid differentiation phenotype. May play a role in lung development and surfactant homeostasis. Forms a regulatory loop with GRHL2 that coordinates lung epithelial cell morphogenesis and differentiation. Activates the transcription of GNRHR and plays a role in enhancing the circadian oscillation of its gene expression. Represses the transcription of the circadian transcriptio [...] (401 aa)

KRT7
Keratin, type II cytoskeletal 7; Blocks interferon-dependent interphase and stimulates DNA synthesis in cells. Involved in the translational regulation of the human papillomavirus type 16 E7 mRNA (HPV16 E7); Keratins, type II (469 aa)
     
   
  0.835
KRT5
Keratin, type II cytoskeletal 5; Keratins, type II (590 aa)
           
  0.735
CTSD
Cathepsin D; Acid protease active in intracellular protein breakdown. Plays a role in APP processing following cleavage and activation by ADAM30 which leads to APP degradation. Involved in the pathogenesis of several diseases such as breast cancer and possibly Alzheimer disease; Cathepsins (412 aa)
       
 
0.688
ALK
ALK tyrosine kinase receptor; Neuronal receptor tyrosine kinase that is essentially and transiently expressed in specific regions of the central and peripheral nervous systems and plays an important role in the genesis and differentiation of the nervous system. Transduces signals from ligands at the cell surface, through specific activation of the mitogen-activated protein kinase (MAPK) pathway. Phosphorylates almost exclusively at the first tyrosine of the Y- x-x-x-Y-Y motif. Following activation by ligand, ALK induces tyrosine phosphorylation of CBL, FRS2, IRS1 and SHC1, as well as o [...] (1620 aa)
     
 
  0.673
CDX2
Homeobox protein CDX-2; Involved in the transcriptional regulation of multiple genes expressed in the intestinal epithelium. Important in broad range of functions from early differentiation to maintenance of the intestinal epithelial lining of both the small and large intestine; HOXL subclass homeoboxes (313 aa)
           
  0.670
PAX8
Paired box protein Pax-8; Transcription factor for the thyroid-specific expression of the genes exclusively expressed in the thyroid cell type, maintaining the functional differentiation of such cells; PRD class homeoboxes and pseudogenes (450 aa)
           
  0.669
KRT20
Keratin, type I cytoskeletal 20; Plays a significant role in maintaining keratin filament organization in intestinal epithelia. When phosphorylated, plays a role in the secretion of mucin in the small intestine (By similarity); Keratins, type I (424 aa)
