Eukaryotic translation initiation factor 6 (EIF6), also known as Integrin beta 4 binding protein (ITGB4BP), is a human gene.[1]

Hemidesmosomes are structures which link the basal lamina to the intermediate filament cytoskeleton. An important functional component of hemidesmosomes is the integrin beta-4 subunit (ITGB4), a protein containing two fibronectin type III domains. The protein encoded by this gene binds to the fibronectin type III domains of ITGB4 and may help link ITGB4 to the intermediate filament cytoskeleton. The encoded protein, which is insoluble and found both in the nucleus and in the cytoplasm, can function as a translation initiation factor and catalyzes the association of the 40S and 60S ribosomal subunits along with eIF5 bound to GTP. Multiple transcript variants encoding several different isoforms have been found for this gene.[1]

Interactions [link]

EIF6 has been shown to interact with FHL2,[2] ITGB4[3] and GNB2L1.[4]

Mrame a los Ojos

by: OV7

Dices que oyes voces casi cada noche, crees que te voy a engaar. Ven, no te equivoques, sintate, se un hombre, aclaremos dudas y en paz, si los amigos no me ven suficiente bien para ti, me importa un higo, eres tu, solo tu, quien vas a decidir... Mrame a los ojos, no dir nada, mira mis ojos, no me des la espalda. Mrame a los ojos, sobran las palabras, mira mis ojos ve lo que siento. Mrame a los ojos, no dir nada, mira mis ojos, no me des la espalda, mrame a los ojos, sobran las palabras, mira mis ojos, dime lo que ves ah. Desde los zapatos a lo que hay debajo, el peinado, todo, te di. Sin trampa ni cuento, ni gato encerrado, tal como tena que ocurrir. Hoy si tu mano toma fuerte la ma, es elctrico, la adrenalina, nos coloca a los dos, creo que esto es amor... Mrame a los ojos, no dir nada, mira mis ojos, no me des la espalda, mrame a los ojos, sobran las palabras, mira mis ojos, ve lo que siento por ti... Mrame a los ojos, mira mis ojos, mrame a los ojos, mira mis ojos. Hoy si tu mano toma fuerte la ma es elctrico, la adrenalina nos coloca a los dos, creo que esto es amor. Mrame a los ojos, no dir nada....... Mrame a los ojos ve lo que siento por ti.
