retrotransposon-like 1; Plays an essential role in capillaries endothelial cells for the maintenance of feto-maternal interface and for development of the placenta (By similarity) (1358 aa)

SMAD family member 4; Common SMAD (co-SMAD) is the coactivator and mediator of signal transduction by TGF-beta (transforming growth factor). Component of the heterotrimeric SMAD2/SMAD3-SMAD4 complex that forms in the nucleus and is required for the TGF-mediated signaling. Promotes binding of the SMAD2/SMAD4/FAST-1 complex to DNA and provides an activation function required for SMAD1 or SMAD2 to stimulate transcription. Component of the multimeric SMAD3/SMAD4/JUN/FOS complex which forms at the AP1 promoter site; required for syngernistic transcriptional activity in response to TGF-beta. [...] (552 aa)

thyrotropin-releasing hormone; Functions as a regulator of the biosynthesis of TSH in the anterior pituitary gland and as a neurotransmitter/ neuromodulator in the central and peripheral nervous systems. May promote hair shaft elongation, prolonge the hair cycle growth phase (anagen) and antagonized its termination by TGFB2. May also increase proliferation and inhibited apoptosis of hair matrix keratinocytes (242 aa)

solute carrier organic anion transporter family, member 1C1; Mediates the Na(+)-independent high affinity transport of organic anions such as the thyroid hormones thyroxine (T4) and rT3. Other potential substrates, such as triiodothyronine (T3), 17-beta-glucuronosyl estradiol, estrone-3-sulfate and sulfobromophthalein (BSP) are transported with much lower efficiency. May play a signifiant role in regulating T4 flux into and out of the brain (By similarity) (730 aa)

family with sequence similarity 129, member B; May play a role in apoptosis suppression. May promote melanoma cell invasion in vitro (746 aa)

solute carrier family 7 (amino acid transporter light chain, L system), member 8; Sodium-independent, high-affinity transport of small and large neutral amino acids such as alanine, serine, threonine, cysteine, phenylalanine, tyrosine, leucine, arginine and tryptophan, when associated with SLC3A2/4F2hc. Acts as an amino acid exchanger. Has higher affinity for L-phenylalanine than LAT1 but lower affinity for glutamine and serine. L-alanine is transported at physiological concentrations. Plays a role in basolateral (re)absorption of neutral amino acids. Involved in the uptake of methylme [...] (535 aa)

solute carrier family 16, member 2 (thyroid hormone transporter); Very active and specific thyroid hormone transporter. Stimulates cellular uptake of thyroxine (T4), triiodothyronine (T3), reverse triiodothyronine (rT3) and diidothyronine. Does not transport Leu, Phe, Trp or Tyr (By similarity) (613 aa)

type III iodothyronine deiodinase ; Responsible for the deiodination of T4 (3,5,3’,5’- tetraiodothyronine) into RT3 (3,3’,5’-triiodothyronine) and of T3 (3,5,3’-triiodothyronine) into T2 (3,3’-diiodothyronine). RT3 and T2 are inactive metabolites. May play a role in preventing premature exposure of developing fetal tissues to adult levels of thyroid hormones. Can regulate circulating fetal thyroid hormone concentrations throughout gestation. Essential role for regulation of thyroid hormone inactivation during embryological development (304 aa)
