Alignm

ent of the cytoplasmic S

IRP

protein sequences. Alignm

ents were perform

ed using the ClustalW

algorithm (version 1.82)

employing the follow

ing sequences: rat SH

PS

-1 (gi_6671640), mouse S

HP

S-1 (gi_1777354), and hum

an SIR

P

1 (gi_2052056). The

two proline-rich regions are overlined and the tyrosine and proline residues are highlighted in blue and red, respectively. T

he proline residues that, at least in case of the hum

an SIR

P

1, are dispensable for JAK

2 binding (42) are indicated by arrows.
